The U.S. Supreme Court is to expected to review Arizona's controversial immigration law known as SB 1070 on Wednesday.
It's hard to imagine the court would uphold the measures of the law that have already been blocked by lower courts.
The most controversial part of the law would allow local police to check the immigration status of anyone they stop and also require that person to show proof of legal status. Those who opposed the law feared this would lead to racial profiling of all Latinos.
One question the court is expected to address is whether it is within federal or local jurisdiction to enforce immigration law. The lower courts over the years have ruled against local immigration laws dating back to a 2007 housing ordinance in Farmers Branch, Texas, that would have banned renting to undocumented immigrants.
The Supreme Court decision will have implications for Arizona and more than a dozen other states, including Alabama, that have passed immigration laws at the state level.
The outcome will be closely watched by Latino voters.
If the court upholds the Arizona law, that could result in a backlash against Republicans. It could give the Democrats a cause under which to help mobilize Latino voters.
They need this because many Latinos are already angry over Obama's immigration policies that have led to the deportation of more than one million people.
If the court strikes down the law, it could be seen as a victory for the Obama Administration.
Republicans have already alienated Latino voters with their anti-immigrant rhetoric during the Republican debates.
Only 14 percent of Latino voters said they would vote for Mitt Romney, according to a Fox News Latino poll released in March. This is far from the percentage of Latino voters won by Sen John McCain, 31 percent in 2008, and by President George W. Bush, 40 percent in 2004.
Romney can't catch up even with Cuban-American Sen. Marco Rubio's help.
All this comes at a time when Mexican immigration is at a standstill.
The Pew Hispanic Center released a study Monday that shows net Mexican migration has fallen to zero or less.
The study found that from 2005 to 2010, about 1.4 million Mexicans immigrated to the United States and about 1.4 million Mexican immigrants and their U.S.-born children moved from the United States back to Mexico.
The weak economy along with immigration enforcement are some of the reasons migration has not increased, according to the study.
The idea that undocumented immigrants from Mexico are flooding into the United States is not true.
The notion that they are an overall drain on the economy and taking jobs away from U.S. citizens also has not been proven.
Undocumented immigrants pay sales to property taxes. They also pay billions into Social Security. One report put the number as high as $11 billion.
Laws like SB 1070 are based on fear more than reality. The Supreme Court should strike this law down.
