A politician in Mexico is proposing a law that could regulate social media sites like Twitter.

Nazario Norberto Sánchez said that social networks like Twitter help narcotraffickers to drunk drivers, according to an article in the Global Post published this week.

"We have to regulate these websites to make sure there aren't people breaking the law, making death threats or committing crimes via electronic means," Norberto told the Global Post.

I also found a Spanish-language story about this topic by Notimex, a Mexican news agency, that was published in Milenio newspaper Jan. 8.

People in Mexico City have used Twitter to avoid DUI checkpoints. In fact, there is a Twitter feed Anti Alcoholimetro that has listed the check points in that metropolis of 20 million, and it has more than 6,000 followers. But now that site has protected Tweets so I couldn't view them.

There also are worries that drug traffickers use Twitter and other social media like Facebook or MySpace to locate targets.

It has been 11 years since Jesus G. "Chuy" Garcia has held political office.

He's made a comeback and was elected a Cook County Commissioner in the 7th District defeating incumbent Joseph Mario Moreno.

"I am elated," said Garcia who claimed victory while surrounded by hundreds of supports at Mi Tierra, a Mexican restaurant in Little Village, where he celebrated election night.

"I feel vindicated tonight by this victory because of the way that I suffered my first loss 11 years ago due to a political gang that was orchestrated against me and negative campaigning that resulted in my defeat," Garcia told me in an interview. "But most importantly I'm excited tonight because I see the emergence of a new Democratic potential."

Garcia, a former alderman, lost his third bid for state senator in 1998. He was defeated in large part by the H.D.O., or Hispanic Democratic Organization that had the backing of the Democratic machine. But the H.D.O. closed its campaign committee in 2008 after federal corruption investigations.

And this in part removed an obstacle for Garcia and for newcomers like Rudy Lozano Jr. who ran for state representative in the 23rd District. Garcia's win and a possible upset by Lozano (the race is still too close to call) signal a victory for reform-minded Latino candidates.

"In my mind we've already won," said Lozano explaining that coming this close is a victory in itself.

By my count there are more than 30 Latino candidates on the primary ballot this Tuesday.

It's great to see so many Latino politicians participating in the political process and many of them have an independent voice. Who knows maybe one day we'll see a Latino mayor of Chicago or a Latino president.

But for now we have plenty of candidates running for a variety of seats from Congress to Cook County Board of Commissioners, Cook County Assessor and the state legislature.

Here are a few of the most interesting races and my picks for who should win.

Jorge Mujica

In the Democratic primary for the 3rd Congressional district, immigrant rights activist Jorge Mujica is challenging incumbent Rep. Daniel Lipinski. Mujica was a lead organizer of the mega marches for immigration reform in 2006 and is a former union organizer. A native of Mexico, he is a dual citizen and has lived in Chicago since 1988.

Lipinski is the son of former Congressman William Lipinski, who was in office for 11 terms, and paved the way for his son's election. He is considered a conservative Democrat who has named Ronald Reagan as his hero. He also is conservative on social issues and immigration.

I support Mujica although I fear he doesn't stand a chance against the Democratic machine that supports Lipinski. That's really unfortunate because Lipinski acts like a Republican and the Democrats should support candidates that reflect their values.

Did you hear that ABC is canceling Ugly Betty?

To be honest I was never a big fan of the show. I watched part of this first season but I quickly lost interest when the plots focused more on romance and intrigue.

Still it's sad to see one of the handful of TV shows that has a leading Latina character go off the air.

What drew me at first to the show was the lovely and curvy actress America Ferrera?

But sadly she too fell under the pressures of Hollywood and grew skinnier with each season.

She stood out in the film "Real Women Have Curves," based on the play and screenplay written by Josefina Lopez (actually a graduate of Columbia College Chicago.)

Lopez actually spoke to some of my students at Columbia last year about her new book and how Latina women are often portrayed as sexpots in the media. And there's incredible pressure for all women in Hollywood to be thin.

That is why at first Ugly Betty appealed to me. She didn't fit any of those stereotypes.

President Obama only made a cursory reference to immigration in his State of the Union speech last night.

He dedicated 37 words of the 70-minute speech to immigration.

"And we should continue the work of fixing our broken immigration system -- to secure our borders, enforce our laws and ensure that everyone who plays by the rules can contribute to our economy and enrich our nation," the president said.

Clearly immigration was an afterthought at the end of his speech.

And he emphasized more border enforcement and law and order without specifically saying he supports any kind of program to help people become legal permanent residents. He said so in the past but it wasn't clear in his speech.

The president's speech was a disappointment to immigrant advocacy organizations.

Will President Obama even mention immigration reform in his speech tonight before Congress and the nation?

Members of the Cook County Board of Commissioners are trying to apply some pressure.

On Tuesday, the Cook County Board approved a resolution urging Congress to support immigration reform.  It passed 13 to 3.

But I wouldn't expect much from the president.

Obama will instead spend tonight talking about strengthening the economy and the need for health care reform.

These are important issues. But now health care reform and anything else the Democrats want to pass has been virtually doomed by the election of Republican Scott Brown to the U.S. Senate. I'm so angry at the people of Massachusetts. Most of them have health care anyway. They've screwed that up and a lot more up for the rest of the country.

I was in Peru's Machu Picchu, one of the modern wonders of the world, just 11 days ago.

It was slightly rainy and foggy but that did not stop us from appreciating the incredible beauty and spiritual energy of the famous archaeological ruins.

But in recent days mudslides have stranded as many as 2,000 tourists in the town of Aguas Calientes that is at the foot of Machu Picchu, according to the ANDINA news agency.

They may be airlifted out by helicopter because the Peru Rail train tracks are blocked by mud and water. So far there are no reports of fatalities.

Peru's leading newspaper El Comercio reports that no tourists will be allowed to enter Machu Picchu for the next three days.

I also found an interesting iReport on CNN and also photos of the mudslides on a site called Living in Peru.

Have you donated yet to Haiti?

I did a "Quick Vote" on CNN.com and found that 46 percent answered yes and 54 percent answered no.

What are they waiting for?

I would hope that after the celebrity musical telethon "Hope for Haiti Now" broadcast in 60 countries tonight that more people would donate to help the victims of the earthquake.

Granted, the CNN online poll is not scientific. But as of 8:57 p.m Friday night with 71,636 votes cast not even half the people reported they had donated. I hope this poll is not reflective of the country as a whole and that the telethon raised the $1 billion they are aiming for.

But if actors like George Clooney and Morgan Freeman, former President Bill Clinton and performances by musicians like Madonna, Bono, Shakira and Jennifer Hudson and many others can't convince you to donate, then sorry you have a cold, cold, heart.

I'm back in Chicago now and on this overcast day I am thinking back on my three- week trip in Argentina and Peru.

I miss the architecture, from colonial to baroque, the colors, which are vibrant, and the landscape from the Pacific Ocean in Lima to the lush green mountains outside Cusco, Peru.

So this morning I went through all my trip photos and selected some to share with you.

Hope they bring you some warmth on this gloomy day.
