Michigan Senate|By Jennifer Duffy, April 18, 2014

When Democratic Sen. Carl Levin announced in May of last year that he would retire at the end of this Congress, no one would have guessed that the race to succeed him would be among the most competitive of the cycle. Michigan voters haven’t sent a Republican to the U.S. Senate since 1994. It is also a place where we would have expected Republicans to host a primary between the establishment...

New Hampshire Senate|By Jennifer Duffy, April 4, 2014

The numbers, geography, and timing for Senate Democrats have been challenging from the beginning of this election cycle. They have greater exposure, defending 21 seats compared with only 15 for the GOP. Even...

Senate Overview|By Jennifer Duffy, March 19, 2014

There’s a lot that we have known about the Senate landscape since the start of the cycle. We have known that Republicans would need to score a net gain of six seats to win the majority; that Democrats would be defending 21 seats to just 15 for Republicans; and that the party holding the White House tends to lose large numbers of seats in the Senate, the House or more often both in...
