Former Alaska Gov. Sarah Palin today urged her supporters to call their senators to tell them to vote no on the first vote on healthcare reform scheduled for tonight.

Palin (R) used her new Twitter account to help organize a calling campaign:

Thot I'd stick w tour news on Twitter but can't help digress: Call senators! Tell 'em KILL THE BILL tonite;horrible govt healthcare takeover

Senate healthcare takeover debate begins in an hour. Pls call senators if u care about another 1/6th of our economy swallowed up by Big Govt

The Senate is set to take its first procedural vote, a motion to proceed, on healthcare reform at 8 p.m. Saturday. Meanwhile, Palin is on a book tour to promote her memoir, Going Rogue: An American Life.

Republicans are expected to unanimously oppose the motion. Two centrist Democratic holdouts, Sens. Mary Landrieu (La.) and Blanche Lincoln (Ark.) still have not said whether or not they will vote for the motion.
