Colorado Senate Election 2010: Ken Buck (R) 46%, Incumbent Michael Bennet (D) 41%

In the first Rasmussen poll following the primaries in Colorado, Republican challenger Ken Buck has a 46% to 41% lead over incumbent Democrat Michael Benett for the Colorado US Senate seat.

Buck attracts 46% support, while Bennet picks up 41% of the vote. Five percent (5%) prefer some other candidate in the race, and seven percent (7%) remain undecided.

Both men won hotly contested party primaries on Tuesday, but Colorado Republicans appear to have come back together a bit quicker than Democrats. Buck now gets 88% support from GOP voters, while 79% of Democrats support Bennet. The Republican leads by just five points among voters not affiliated with either party.

These results are similar to those from before the primary.

The Colorado US Senate election is considered a toss-up; however, Republicans have lead in the polls most of the way. The most pressing issue in Colorado is the economy. Voters in the state have a pessimistic view of the economy. Just 4% rate the economy as good, while 65% describe it as poor. Other polling shows that 25% say the economy is getting better, while 50% say it’s getting worse. With the economy and jobs not getting any better, it is hard to imagine that CO voters will not blame the party in power come the midterm elections. A Buck victory in November 2010 would represent yet another GOP pick up in their efforts to take back control of the US Senate.
