Moving to the Senate campaign, the Hill reports that in two of the most hotly contested races, the candidates are going to court:

Sen. Norm Coleman (R-Minn.) has sued Democratic opponent Al Franken for defamation, claiming that Franken's television ads make false accusations about Coleman being the fourth most corrupt senator in Washington.  ...

The Coleman-Franken race is the second hotly contested Senate fight in two days to draw legal action. On Wednesday, Democrat Kay Hagan's campaign filed a cease-and-desist letter over Sen. Elizabeth Dole's (R-N.C.) ad that suggested Hagan, a former Sunday school teacher, was an atheist.

Looking at the RCP Avgs, Coleman has a 2.4-point lead over Franken, while Hagan has a 3.2-point lead over Dole.
