A new poll has come to light, showing Republican Mike Fallon trailing longtime paperweight Representative Diana DeGette by only 10 points, with DeGette unable to break 50%.  The telephone poll of 700 likely voters has DeGette at 44%, Fallon at 34%, and the undecideds at 22.5%.  The poll was conducted by ccAdvertising, one of the larger national Republican polling firms, and has a margin of error of 3%.

A couple of things to note.  First, as mentioned above, DeGette is under 50% in a district she’s held for, well, forever.  The pollsters did adjust for expected voter turnout, using a fairly complex model.  I have no idea how their track record for accuracy compares to, say, Rasmussen.

I also note that the sample appears to over-weight Republicans considerably, with the D-R-U breakdown coming in at 40-31-28.  The actual voter registration in Denver is about 50-20-30.  That said, the party breakdown is a result of voter self-identification.  The pollsters apparently called in the prevailing proportions, but about 10 percentage points’ worth of Democrats refused to identify themselves as Dems, calling themselves Republicans or unaffiliated instead.  How to treat party identification is an unresolved problem in poll methodology, but in this case, the pollsters are also trying to account for expected turnout, and probably used self-identification as a response rather than a demographic.

Again, assuming the pollsters called representative proportions of likely voters, 48% of those responding favor repealing Obamacare, while 52% oppose.  This is more favorably disposed to Obamacare than the national average, but indicates a high level of dissatisfaction with the law even in a heavily Democrat area like Denver, and is no doubt contributing to Fallon’s support.  Mike’s an ER doctor, and has made actual health care reform a keystone of his campaign.

Does this mean that the race is winnable?  That last 10 points is going to be awfully hard to make up, but the pollsters look at that 22% undecided as a gold mine of potential votes.  After 18 years, DeGette’s a known quantity, and she probably can’t say much about herself that will move the needle in her direction.  More Republicans are undecided than Dems, indicating, perhaps, that they still haven’t heard much about Mike. And over 45% of Unaffiliated voters are undecided.  Of those unaffiliated voters, though, many are probably Dems no longer willing to call themselves Dems to pollsters, who are still probably inclined to vote Democrat.  ccAdvertising thinks that the undecideds could well break 9-1 for Mike.  While I think that’s an extraordinarily optimistic projection, in reality, they’d only have to break a little better than 5-2 for him to actually win the seat, assuming that the partisan breakdown is correct.

All in all, this has got to be good news for Fallon; I just wish it had come a month ago.
