Colorado is one of the battleground states where Republicans made big gains this week. Republicans in the state believe they now have momentum going into the 2016 presidential election.
But the GOP has suffered some punishing losses there lately, owing in part to the state's changing demographics. That trend may still be a big factor in 2016.
The last time Republicans won a U.S. Senate seat here was when Wayne Allard was re-elected in 2002. Back then, Congressman and now Senator-elect Cory Gardner was a young staffer working behind the scenes for Allard.
