There haven't been a lot of good weeks on the Senate election front for Democrats so far in 2010, but they have received good news on their chances of picking up five different Republican held Senate seats this week:
-In Arizona there have been two polls now showing John McCain under 50% against Rodney Glassman. J.D. Hayworth continues to be competitive among Republican primary voters against McCain, and it appears a Hayworth-Glassman contest would be a total tossup.
-In Iowa Research 2000 showed Charles Grassley only up single digits against Roxanne Conlin, and although Rasmussen has Grassley up by 13 that's a far cry from January when they showed him leading her by 28 points.
-In Kentucky we found both Jack Conway and Dan Mongiardo within the margin of error against Rand Paul, who all independent public polling continues to show with a double digit lead.
-In North Carolina, Rasmussen showed Elaine Marshall improving her standing against Richard Burr by ten points in just two and a half weeks and Cal Cunningham with a nine point movement in his. If we find anywhere near that much momentum for Marshall and Cunningham on our North Carolina poll this weekend then we'll find each of them almost tied with Burr for the first time.
-In Ohio Quinnipiac and Rasmussen now both show Lee Fisher ahead of Rob Portman, and in the case of Rasmussen that's a six point improvement for Fisher over the last month. Even if his primary victory wasn't exactly overwhelming, his standing's improved.
One thing we really don't know for sure yet is whether 2010 will be solely an anti-Democratic year, or more broadly an anti-incumbent year where there are some surprising Republican losses in addition to the expected Democratic ones. Although the GOP still has to be seen as favored in all of these races, the movement in a Democratic direction in each of them is an encouraging sign for the party.
