Palin's political action committee, SarahPAC, gave Romney's campaign $5,000 last week, a near-last-minute show of support in the final days before the election. 

Palin, while fervent in her opposition of President Obama, had not been full-throated in her support of Romney as the GOP nominee. She voted for Newt Gingrich in the GOP primaries. 

She did signal her support of Paul RyanPaul Davis RyanNew Dem ad uses Paterno, KKK, affair allegations to tar GOP leaders House Dem: Party's aging leaders is 'a problem' Rand Paul to ask Trump to lift sanctions on Russian leaders MORE as Romney's choice of running mate.

But in a 922-word post early Monday, Palin urged her many supporters to get out the vote Nov. 6 for Romney and "the many good Republican candidates who are running for the House and Senate this year."

"Tuesday is our chance to turn things around," she wrote, arguing that Obama has "transformed us from a nation of hope to one of anxiety."

Since resigning as governor of Alaska, Palin has remained an influential conservative pundit in the political world as a contributor to Fox. She frequently uses her Facebook page as a direct form of contact with her many supporters.
