Even if Beauprez wins I still expect the CO House to stay in Democratic hands because the lines are drawn favorably towards them. They won't let him repeal anything they've passed especially the new voter laws.
The CO legislature would only go R in a landslide election?
Probably. The Dems have likely already lost the Senate, but the House is a steep climb for the GOP.
Then again, the two generic ballot polls in Colorado that I've seen were R +7 (PPP) and R +6 (Suffolk). Those are massive numbers. But I also recall the GOP having a generic test ballot lead in 2012, and that didn't work out so well, either. My hunch is that the GOP will have a slim majority in the Senate and the Dems will lose a few House seats but keep a slim majority.
So, in the long run, Colorado will probably stay at parity? I'd rather lose this election and keep at least part of the Legislature so that Democrats get the chance to regroup without losing their achievements so far. To be honest, they went too far on gun control and aren't giving the devil its due on fracking (it is cleaner than oil and coal) but I don't want Republicans passing personhood laws, allowing drilling near neighborhoods or near good hunting and fishing areas or believing its the public school's job to make sure kids become Republican.
