In a last-minute show of support, Sarah Palin posted a Facebook note urging Republicans to back Mitt Romney.
"On Tuesday, please vote for Governor Mitt Romney and the commonsense conservatives running for office in your state," wrote the former governor of Alaska. "Governor Romney understands how the free market works...Governor Romney deserves a chance to lead. President Obama had his chance."
Palin still has a lot of influence with Tea Party voters, and her support could mobilize them to get out and vote for Romney. Her endorsement is perhaps all the stronger for being delayed so long. Previously, Palin warmly endorsed Newt Gingrich and seemed pretty lukewarm in her feelings for Romney.
