Mormons are 2% of the population in that part of the country, Colorado. Not sure what you mean about the rest. My point is that Colorado has been trend-setting all kinds of minority breakthroughs lately in the few years, from gays to blacks to Native Americans to Mormons to Hispanics.
Obviously he's not that big of a guy, but he was elected city-wide in a legitimately big city and he has a serious chance at being a serious contender (this is my argument). We'll see. Sometimes candidates emerge out of nowhere. I've always bet my money on Bennet being a serious candidate, if not a national candidate, some day. But, if the GOP takes him down this year, which is one of their most likely opportunities (after CT and NV), this guy may be the third most likely Republican to defeat a Democratic seat ... in the country ... which isn't saying much because it's 2010. But even NV isn't shaping up too well..
Colorado's GOP has gone through a transformation similar to Pennsylvania, the Republican Party in the state is mu.ch more conservative than it use to be as the moderate Republicans have fled the party in droves. The state party is ultra-conservative (which is a big reason they are getting destroyed in the state) and unless that changes the chances of a moderate African American getting past a statewide Primary is almost zilch.
