Rasmussen Reports, one of the more conservative (in the methodological, not political, sense) public opinion polling organizations, now says it looks like a dead heat in the Senate. 48 seats will go to the Democrats, and 48 to the Republicans. Four seats, Missouri and Virginia, remain "toss ups."
In Missouri, Claire McCaskill holds a tenuous one point lead over Republican incumbent Jim Talent. In Virginia, Jim Webb and George Allen both command 49% of the vote. In Montana, Jon Tester holds a two point lead over Republican incumbent Conrad Burns. And in Tennessee, Republican Bob Corker holds a four point lead over Harold Ford.
Pennsylvania's Rick Santorum will be replaced by Democrat Bob Casey. Sherrod Brown looks to crush Mike Dewine in Ohio.
