As this chart clearly shows, any complaints about Palin “quitting” her job 18 mos early by liberals can easily be compared to the paltry record of Obungler’s record.
He was present for two years of his six year term, then essentially left the Senate to campaign for President on the dole of the U.S. Government from January 2007 to December 2008, then resigned for the last 2 years.

He served 1/3 of a 6-year term. Palin quit the last 18 mos of her 4-year term, over half-way through.
