Republican presidential candidate Mitt Romney and running mate Paul Ryan are scheduled to visit Colorado next week.
    
The two have planned a rally at the famed Red Rocks Amphitheatre on Tuesday night, the day after early voting begins.
    
Romney, President Barack Obama, their running mates and spouses have been busy visiting battleground states in the weeks leading up to Election Day. Though Obama won Colorado in 2008, Republicans have said they consider the state to be in play this time around.
