The conservative Daily Caller reports on a new poll conducted for Republican-aligned SuperPAC American Crossroads on the Colorado U.S. Senate race:
Incumbent Colorado Democratic Sen. Mark Udall has a slim lead over his challenger, Republican Rep. Cory Gardner, according to a new poll from American Crossroads.
Forty-five percent of those polled said they would vote for Udall, compared to 43 percent for Gardner. Twelve percent of respondents aren’t sure who they will vote for.
Udall’s lead is well within the poll’s 4.35 percent margin of error, meaning that the contest remains a dead heat.
In terms of favorability, voters’ opinion of Udall is almost evenly split, with 41 percent saying they have a favorable opinion of him to 42 percent unfavorable.
Their opinion of Gardner, however, is more clearly divided, with 38 percent unfavorable to 30 percent favorable. But 32 percent aren’t sure.
Here's the memo from Harper Polling.
This conservative leaning poll has a fairly high margin of error at 4.35%, and uses automated methodology that we really don't think is as accurate as live interviews. Despite these caveats, it's interesting that a month of high-volume attacks on incumbent Democratic Sen. Mark Udall do not appear to have moved the needle against him at all–Udall still polls narrowly ahead of challenger Cory Gardner. We'll want to see more polling to establish that clearly, but as a Republican strategist, you can't look at unchanged polls after shoveling money into attack ads against Udall over "Obamacare" for a month and feel good about it. If that's right, Americans for Prosperity and friends just wasted a pile of Koch Brothers money.
