Granby, Colorado (CNN) -- In my American Quest I am visiting states firmly for President Barack Obama (Illinois), those strongly for Mitt Romney (Utah) and some, like my next train stop, which can't make up their minds. Colorado, is one of these "undecided" states, which have become crucially important. A look back shows Republicans won eight out of the last 10 presidential elections here, and in an interesting twist, Colorado also picked the election winner in eight of those 10 elections too. The exceptions of course were the Democrat victories of Bill Clinton in 1992 and Obama in 2008. In other words, Colorado stays Republican until it sees a Democrat it likes, and then that man wins the election.
