In case the Democrats didn't have enough challenges going into the 2012 elections, Republican lawmakers in several states are rewriting election laws. A dozen states have passed more restrictive voter ID laws, though four Democratic governors vetoed them. Florida and Ohio halved the days available for early voting, and Florida rolled back a law that made it easier for felons to vote. The moves may keep young people and minorities away from the ballot box. Pennsylvania lawmakers are considering divvying up electoral votes by congressional district rather than giving them all to whoever wins the state. That change would likely result in a gain of 20 to 24 electoral votes for the GOP.
