I expect Jane Norton to beat Udall in 2014.
The CO GOP is similar to the Kansas GP. A good chunk is too conservative for the state and the rest is moderate. There's constant infighting and it often lets democrats have the upperhand.
The CO democratic party is a well-oiled machine. They have a terrific warchest of candidates and they push the right buttons that sell around the DEMOGRAPHICS of the state, something the GOP continues to ignore there. They act as if this is 1990 CO and it's not (similar to the GOP in VA).
