| Public Policy Polling (9/30-10/2, likely voters, 8/7-8 (RVs) in parentheses, gubernatorial numbers here):
Michael Bennet (D-inc): 46 (46)
Ken Buck (R): 45 (43)
Undecided: 9 (12)
John Hickenlooper (D): 47 (48)
Dan Maes (R): 13 (23)
Tom Tancredo (C): 33 (22)
Undecided: 7 (7)
Michael Bennet has the slimmest of leads in Colorado according to PPP, the pollster who've tended to be the most favorable to him. It's an enthusiasm gap thing, although not as bad as in the midwest: if their August RV model were used, Bennet would lead 47-44 (and if the 2008 turnout model were used, he'd lead 50-41). Bennet's approval is 35/49, while Buck is at 41/46.
On the gubernatorial front, Dan Maes has collapsed even further as his amateur-hour campaign leaks air; he's down to 12/58 favorables (from 23/38 in their last poll). In a way, that's bad news for John Hickenlooper, who needs a healthy split between the two conservatives instead of seeing Maes dwindle down into single digits, which may actually be possible given the current trajectory. Hickenlooper's personal popularity (51/37) seems like it'll be enough to help him weather even a complete Maes collapse, though.
Harstad Strategic Research (10/3-4, likely voters, no trendlines):
Michael Bennet (D-inc): 44
Ken Buck (R): 41
For good measure, there's also a poll of the Senate race out from Democratic pollster Harstad giving Michael Bennet a 3-point lead, and also finding Ken Buck with a 31/41 favorable. (Apparently this poll is from the Bennet campaign, though the memo doesn't explicitly say.) I'm still not feeling terribly optimistic about this race, given that most other pollsters looking at this race have given Buck a mid-single-digits lead -- and a leaked Dem poll with a 3-point lead doesn't do much to encourage more optimism, but at least it plus the PPP poll show that the race is still in tossup territory.
