Snowe is still pretty popular with the liberal/moderate wing of her party, earning a 64% approval rating from them. But even in Maine 68% of Republicans are conservatives and they give her just a 29% approval rating with a 56% majority disapproving of her.

Asked how they would vote in a primary contest between Snowe and a more conservative challenger, just 31% of likely Republican voters say they would pick Snowe while 59% say they would go for the conservative alternative…

Snowe’s overall popularity is still decent, with 51% of voters approving of her to 36% disapproving. That owes to a 60% approval rating with Democrats and a 51% mark with independents.
