ST. LOUIS, Missouri (CNN) – Missouri Senator Claire McCaskill chastised Governor Sarah Palin for recent comments that she likes to visit “pro-American” parts of the United States.

“We have reached a new low in American politics when someone dares to say that one part of America is more pro-American than another part of America,” McCaskill said at an afternoon Barack Obama rally.

McCaskill, an ardent Obama supporter and ubiquitous campaign surrogate said voters are beginning to “see clearly the differences between these two candidates.” She described the Obama campaign as exhibiting the “kind of leadership that America needs in a crisis” because in her mind it has been “slow, steady, thoughtful, constructive.”

McCaskill criticized the McCain campaign as “stumbling, erratic, all over the map” and said it is trying to “distract American with small, petty, unfair personal attacks.”

“As America has taken the measure of these men, they have looked at their judgments on the campaign trail. One picked one of the strongest candidates for vice president he could’ve picked in the United States. The other didn’t,” she said.
