MORRISON, Colo -

 Move over, U2. Here comes Mitt Romney.
    
The Republican presidential candidate was joined by running mate Paul Ryan, Kid Rock and Rodney Atkins for a rally with thousands of supporters at Red Rocks Amphitheatre Tuesday evening. The Republican ticket hoped to use the famous concert venue to juice up the GOP faithful as early voting continues in Colorado. The amphitheater was the setting for the U2 concert film "Under A Blood Red Sky."
    
Also Tuesday, Romney's campaign announced the support of Colorado Rockies first baseman Todd Helton.
    
President Barack Obama visits Denver on Wednesday for an afternoon rally in City Park. The frenzied campaigning marks the end of the presidential race. Polls show an essentially deadlocked contest nationally and in Colorado. That means voter enthusiasm and turnout will be pivotal.
