Sen. Claire McCaskill's job approval rating has remained strikingly consistent over the last year, despite a raucous summer of town hall meetings and a surging national tide against Democrats and President Obama.
McCaskill's most recent approval rating, according to SurveyUSA, is 48 percent.
Throughout 2009, McCaskill's approval has never climbed higher than 54 percent and never dipped below 47 percent in polling with a 4 point margin of error.
In fact, her approval rating over the last 11 months comes in at an average of 50.6 percent.
Compared to the state's two other leading politicians, McCaskill's numbers have remained remarkably stable. The state's senior Republican, Sen. Kit Bond, peaked with a 59 percent approval rating back in February, but fell 14 points to 45 percent in September. Bond's November approval is 47 percent. Gov. Jay Nixon has seen a more consistent decline. In January, he debuted with a 63 percent approval rating. In eleven months, the first-term Democratic Governor has slid 19 points to a November rating of 44 percent approval. McCaskill's rating has swung a total of seven points all year.
