Floridians endured election chaos and marathon voting lines this year, largely thanks to reduced early voting hours, voter purges, and voter registration restrictions pushed by Republican legislators. In an exclusive report by the Palm Beach Post, several prominent Florida Republicans are now admitting that these election law changes were geared toward suppressing minority and Democratic votes.

Former governor Charlie Crist (R-FL) and former GOP chairman Jim Greer (R-FL), as well as several current GOP members, told the Post that Republican consultants pushed the new measures as a way to suppress Democratic voters. Crist expanded early voting hours in 2008 despite party pressure, but Gov. Rick Scott (R-FL) targeted early voting almost immediately when he took office in 2011. Scott’s administration claimed the new laws were meant to curb in-person voter fraud, despite the fact that an individual in Florida is more likely to be struck by lightning than commit voter fraud.

Current party members and consultants confirmed the motive was not to stop voter fraud but to make it harder for Democrats and minorities to vote:

House Majority Leader Mike Turzai (R-Allegheny) suggested that the House’s end game in passing the Voter ID law was to benefit the GOP politically.

“We are focused on making sure that we meet our obligations that we’ve talked about for years,” said Turzai in a speech to [Republican State Committee] members Saturday. He mentioned the law among a laundry list of accomplishments made by the GOP-run legislature.

“Pro-Second Amendment? The Castle Doctrine, it’s done. First pro-life legislation – abortion facility regulations – in 22 years, done. Voter ID, which is gonna allow Governor Romney to win the state of Pennsylvania, done.”

under Section 2 of the VRA, NOT Section 5 at issue now, so Wisc can seek remedies, as can those injured ANYWHERE in the country,

Why do Ohio Republicans suddenly feel so strongly about limiting early voting hours in Democratic counties? Franklin County (Columbus) GOP Chair Doug Preisse gave a surprisingly blunt answer to the Columbus Dispatch on Sunday: “I guess I really actually feel we shouldn’t contort the voting process to accommodate the urban—read African-American—voter-turnout machine.” Preisse is not some rogue operative but the chairman of the Republican Party in Ohio’s second-largest county and a close adviser to Ohio Governor John Kasich. -

I don't know what happened with the DMV offices, but the voter ID part of the voting law is currently enjoined by two different state courts, and never went into effect after it was passed in 2011. Both cases are making their way through the Wisconsin appellate system. Even if both cases should be decided against us in the Wisconsin Supreme Court (which is another reason that we need to elect Ed Fallone this April, by the way), there is another case filed in federal court that is on hold while the state cases continue.

As far as I know, Wisconsin is not one of the jurisdictions that need preclearance under section 5 of the VRA, which is at stake in the case argued today. However, the many laws to restrict voting rights, like the one you cite, would indicate we may need another federal law to protect rights in all states.
