Evidence for a wave

I'm sticking with my predictions about the midterm elections, although there are a bunch of anecdotes that would tempt me to move into either the Dems-will-hold-the-House camp or into the Dems-will-lose-8,000-seats camp.

In the latter category, I am hearing rumors that Colorado Democrats are worried about several of their Denver statehouse districts, including HD3, held by Rep. Daniel Kagan, who was appointed to the post last year.  The latest voter registration stats show that HD3 is 40% Democratic and 26% Republican, with 32% unaffiliated.  Is it possible that a Democrat could lose a district like that?  Suffice it to say that if Democrats can't hold onto statehouse seats in Denver, they're not holding onto much else.
