Democratic Senator Michael Bennet appeared in Colorado Springs yesterday to send his supporters a simple message: He needs everyone to vote because his race is the tightest in the nation (via The Gazette). Indeed, poll after poll has shown the two running very closely. The latest was commissioned by political race-horse website ColoradoPols, which found 43 percent of likely voters leaning toward Bennet and 42 percent toward Republican Buck.

Almost $25 million has been thrown at the race by outside groups, points out The Washington Post, making it the "marquee contest in the country for spending by the national parties and third-party groups." The biggest spender in the last week has been the National Republican Senatorial Committee in Washington, D.C.

Yet, despite the funds from the GOP establishment being spent on his behalf, Buck continues to cast himself as a tea-party outsider, telling Fox Business he doesn't support current Republican U.S. Senate leader Mitch McConnell of Kentucky. 

Both of Colorado's senatorial candidates are expected to campaign hard leading up to next Tuesday's election. Buck will be in Colorado Springs today, as Bennet begins a three-day bus tour of the state, notes The Associated Press.
