Some folks are deadly serious about kicking Chicago out of Illinois.According to an AP story published in Pew Research's online magazine, Stateline:
In Illinois, a resolution calling on Congress to declare Chicago the 51st state has eight Republican cosponsors in the state House (there are 44 Republicans in the lower chamber) and support among many of the state’s conservative activists. It’s the second such bill in as many years.
Illinois state Rep. Brad Halbrook, the bill’s author, cites the many issues tearing the state apart. He listed Democrats’ “overreaching” stances on abortion, guns, immigration, debt, pensions, Medicaid spending, property taxes, green energy and workers’ compensation as just some of the reasons Chicago and Illinois should go their separate ways.
It's permissible under the Constitution; it's how West Virginia split from Virginia and Maine from Massacheusetts. It's a fascinating story, well backgrounded and analyzed in the AP story and well worth reading.
