I don't understand your criticism of Quinnipiac in Colorado:
Quinnipiac only polled CO in 2008 and 2012 and in 2008 they had one of the best final CO polls out there, showing Obama winning by 9 (he won by 9).

In 2012, Quinnipiac conducted their CO poll right after Obama's disaster of first debate and of course Romney was up by 1 in this one. Too bad they didn't release a final poll closer to the election.
But in general, Quinnipiac is a solid pollster and they had good results in 2012.

There's another simple explanation for CO and Hillary: She suxx in this state (but that can change during the actual 2016 campaign between summer and election day).
