Just 44 days until Election Day, former President Bill Clinton spoke out on Sunday political talk shows out about controversial measures that will impact advanced voting.

He said on CNN's "Fareed Zakaria GPS" that getting some of President Barack Obama's key supporters to the polls could be a challenge in states like Florida.

"Pre-election voting, advanced voting has been cut down to eight days and doesn't include the Sunday before the election, which is an arrow aimed straight at the churches who pull up the church buses on the Sunday before elections and take elderly people who have no cars or people who are disabled to the polls so they can vote," Clinton said.

Mitt Romney's campaign is trying to rebound after a particularly rough week.

Republican National Committee Chairman Reince Priebus, was on ABC's "This Week," where he came down hard on the president.

"This president thinks he's entitled to four more years? I think he should worry about intelligence briefings, getting the economy back on track instead of debate prep and, you know, interviews," said Priebus.

Republican vice presidential candidate Paul Ryan is campaigning in the battleground state of Florida on Sunday, with a stop in Miami.
