I suppose I should put the disclosure at the top: Sen. Michael Bennet is the brother of James Bennet, the Atlantic's editor.
Why at the top? Because the state of the Colorado Senate Democratic primary is not accurately being reported.
Plenty of polls have showed Bennet leading Romanoff narrowly. In June, SurveyUSA found that Bennet had a 17 point lead -- the only poll ever to show him with anything resembling that kind of margin. Now SurveyUSA has Romanoff ahead by several points. It's a surge...providing you ignore the numerous public polls, both internal and public, that have shown a close race for months. SurveyUSA uses automation to conduct polls, which automatically makes it suspect for many consultants and analysts. (The jury is still out for me.) Romanoff has inched upward in he past few weeks: he's been on the air all the time thanks to money he got from selling his house, and he was endorsed by Bill Clinton.
Romanoff is a well-known and well-liked commodity among Colorado Democrats, having ably served as Speaker of the House. Bennet faces several distinct disadvantages that Romanoff has been able to exploit, including his ties to Washington, his lack of connection to Democratic voters, and the fact that he was a business consultant.
