In this photo taken Sept. 28, 2012, speech pathologist Kelly Kuehl, background right, walks her dog in Denver. Not too long ago this state was political flyover country, a reliable vote for the Republican presidential candidate that was best known for football and skiing. Now it is the epicenter of national politics for the third cycle in a row. Wednesday’s presidential debate at the University of Denver is being touted as a make-or-break moment for Mitt Romney’s campaign. Denver is the third-busiest political ad market in the country during this campaign. In 2010 it was the top as the U.S. Senate campaign here became the most expensive of that cycle. And in 2008, Barack Obama put Colorado firmly on the political map by accepting his party’s presidential nomination at the Democratic National Convention here. (AP Photo/Jae C. Hong) less
