New polling shows that Susan Collins has a problem. A new University of New Hampshire poll shows that only 14% of Mainers view Collins favorably, while 57% view her unfavorably. With numbers like these, she ought to be concerned. In contrast, term-limited Gov. Janet Mills (D-ME) has an approval rating of 51% while 41% of Mainers don't approve of her. Mills has not said if she plans to challenge Collins, but with numbers like these, the Democrats will move heaven and earth to get Mills to jump in and take on Collins. After all, while Collins has won statewide, so has Mills. Collins is no doubt praying that Mills stays out of it. (V)
