Winning in Colorado is all about turnout and not so much about playing to the indies. The GOP is in decent shape to win here if they can nominate someone credible. (Big "if.")
That was true in 2002 but it doesn't really hold water anymore. Colorado is looking to go the way of Washington and Oregon with Republican registration advantage shrinking at a significant rate. In fact, Independents have already surpassed Republicans. That means Indies ARE important and a moderate Republican is needed to win. Fundies cannot win here anymore. Those days are over in Colorado. The problem is that the Republicans in Colorado will probably not nominate a moderate. Whatever. It's their funeral.
