Sarah Palin really has the 2010 congressional elections in her cross hairs now.

As President Barack Obama signed healthcare reform into law, the potential 2012 Republican White House wannabe was out on Facebook with her own campaign to unseat 20 House Democrats who voted for the legislation. The page identifies targeted congressional districts via a map of the United States dotted by white and red cross hairs.

“We’re going to fire them and send them back to the private sector, which has been shrinking thanks to their destructive government-growing policies,” she says in a rallying note to supporters that also seeks donations for her political action committee, SarahPAC.

It’s also an opportunity for Palin to demonstrate some of the political nous and muscle she’ll need in two years, if the former Alaska governor intends to make a credible run for president.  Since the 2008 election, her biggest rise as been as a media celebrity with a best-selling book, a TV gig as Fox News analyst and a possible reality TV show deal. She has made campaign appearances on behalf of Republican candidates up to now. But her new initiative would be her highest profile effort yet.

Weighing in on the 2010 elections also poses risks for Palin, who could lose credibility if the candidates she backs fail. A USA Today/Gallup poll suggests that 49 percent of Americans think the healthcare reform bill’s passage was a good thing, vs. 40 percent who see it as bad. Forty-eight percent called the legislation “a good first step” that needs to be followed up by more action.
