Republican presidential candidate Mitt Romney is campaigning in Nevada and Colorado, the day after his final presidential debate with President Barack Obama.

GOP vice presidential nominee Paul Ryan will join Romney at a rally in Red Rocks, Colo.

Ryan, hitting back against Obama’s “horses and bayonettes” zinger at Monday night’s presidential debate, on Tuesday implied the president’s quip was naïve because “the ocean hasn’t shrunk … you still have to have enough ships to have the footprint you need … to keep our strength abroad where it needs to be. “

Democratic strategist Paul Begala said Democrats have given up on trying to win North Carolina for Obama, and Romney “is likely to carry” the battleground state.
