It is worth noting that Obama underpolled here both times by almost as much as he did in NV. Plenty of final 2012 polls had Romney tied or leading. Also, Hickenlooper beat his polls both times, particularly in 2010 when it looked like he was in an MOE race. While Gardner lost, he was expected to lose by more than he did. All things considered, a Dem should be fairly happy with a bare bones lead in CO in this era.
Obama did overperform his CO polls for sure. He did quite well, with an RCP average of +1.5 and a win of +5.4, so that makes me feel better about this.
However, didn't you mean
"While Gardner won"? He actually matched his RCP average to the T. Average of 2.5, won by 2.5

They have the wrong numbers for Gardner and in fact it seems like a lot of other races. I wonder where they are getting their numbers from.
