NBC NATIONAL NEWS — In the race for the White House, it's not yet the final sprint, but President Barack Obama, Governor Mitt Romney and their running mates hurried from battleground to battleground Wednesday in a frenzy of campaigning that suits a contest too close to call.
The polls are so close that all kinds of combinations of wins in the swing states could lead to a Romney or an Obama victory, so they're hitting them all.
Mitt Romney and Paul Ryan's swing state tour started in Colorado.
They split up, with Romney going to Nevada, where he trails by three points.
Ryan went to Ohio, where he and Romney have tightened a five point gap down to one.
Colorado could be key.
The Obama lead in the state has disappeared.
To slow the slide President Obama will visit five swing states, starting in Iowa where his lead is down to two points
Like Paul Ryan, Joe Biden was in the Buckeye State, which many see as the must-win contest.
"Everyone always says no Republican has been elected president without Ohio, and that's absolutely true, but you know every four years we break rules" says Professor Larry Sabato, director of the University of Virginia's Center for Politics.
The Obama plan is to take Ohio, plus Iowa and Wisconsin or New Hampshire or Colorado, and maybe Virginia.
"The problem for the President is he has leads in these swing states by two, three points. The problem is he's not over 50 percent in any of them," notes Tom Bevan of Real Clear Politics.
The pace will remain intense.
Governor Romney heads to Iowa next.
President Obama will appear on "The Tonight Show", then head on to Nevada.
From there Air Force One will fly to to Florida for Thursday's swing state push.
