The Senate race in Colorado is almost neck-and-neck, with Democrat Michael Bennet closing in on Republican Ken Buck and narrowing his lead to 3 points, according to a Reuters-Ipsos poll.
But the enthusiasm gap favors Republicans, with 72 percent saying they are certain to vote in the Nov. 2 midterm elections compared with 55 percent of Democrats.
The Senate contest pits Bennet, who was appointed to the seat vacated by Ken Salazar when he became President Barack Obama’s Interior Secretary, and Buck, who is backed by the conservative Tea Party movement.
Former President Bill Clinton showed up in Denver late Monday to campaign for Bennet, which was notable because he had endorsed Bennet’s rival in the Democratic primary.
Colorado is one of the races seen as a guage of how strong the anti-incumbent mood is among voters largely worried about the economy and whether Tea Party candidates can generate broad appeal.





narrowly defeated former Lieutenant Governor Jane Norton. Buck, a former prosecutor, won despite being caught on tape complaining about Tea Party “dumb-asses” who question whether Obama was born in the United States. He will face Bennet in November.
