In the political rhetoric of the sprawling, overwhelmingly rural Fourth Congressional District in Colorado, Denver seems to get about as much respect as does Washington, which is to say not a lot. Democrat Betsy Markey is running for reelection in this swing district as an independent-minded loyal local, a Fort Collins gal. Her opponent, Republican Yuma state Rep. Cory Gardner, plays down the time he spends at the Capitol in Denver as much as he does his career history as a lawyer. He talks instead about Yuma and working to sell tractors with his father and grandfather. When Markey and Gardner want to raise cash, though, its not their own district that brings in the bucks. Like pretty much every other politician in Colorado, the real dollars come from Denver.
