The Real Clear Politics (RCP) average of polls shows Romney has gained ground on the president — and has taken the lead outright in Colorado, Florida and North Carolina. With the prospect of a close Romney win becoming more and more believable, some Republicans have begun to make sure they’ve tied all lose ends that may move right-leaning votes away from Romney, for example, towards Gary Johnson.

The New York Times reports that aides to Romney say Johnson is more likely to hurt Obama in the potentially critical state of Colorado, where a marijuana initiative Johnson supports is expected to draw young voters to his cause on Election Day.
