Love 'em or hate 'em, Sarah Palin's tweets command media attention like those of few other political figures. The former governor of Alaska has used Twitter to delve into a host of issues, like cheering on daughter Bristol on the reality show Dancing with the Stars, blasting Obama's "very wrong" tax policy, endorsing midterm candidates and most famously asking "Peaceful Muslims" to "refudiate" the proposed Islamic center near Ground Zero. That last tweet prompted Palin to compare herself to Shakespeare because of their shared fondness of coining new terms. She might have been half-kidding, but Palin's Twitter prowess is no joke.
