Rasmussen: Romney edges Obama in swing-state Colorado

Romney leads with 47 percent support over Obama at 45 percent, according to the survey of 500 likely voters. That's within the poll’s 4.5 percent margin of error.

Colorado is a true toss-up, with Obama holding a 1.7 percent lead in the Real Clear Politics average of polls.

Obama won the state easily over Sen. John McCain (R-Ariz.) in 2008, 54 to 45 percent. It was only the second time since 1968 Colorado has gone for the Democratic presidential candidate.
