SAN FRANCISCO (AP) -- Exactly one month from Election Day, Republican Mitt Romney and President Barack Obama are both declaring they will win a race for the White House that remains anything but clear.
Obama plans a rally at Ohio State University today, the last day for Ohioans to register to vote.
Romney is set to campaign in Iowa and then Ohio, two of the nine contested states on the path to 270 electoral votes. He is expected to attend a midday rally in Van Meter, near Des Moines, then a night rally near Akron, Ohio.
Obama maintains more paths to victory, but polling shows a tightening race after more than 67 million people watched Romney shine in the Denver debate last week.
Yet Romney's path victory is extremely narrow, particularly without Ohio.
