New numbers from the swing state of Iowa show a toss-up with Romney picking up 47% of the vote to Obama’s 46%. In that state, Romney has a 10-point advantage on the question of who is trusted more to deal with the economy.

The race is also a toss-up in Ohio, Virginia, Florida and Colorado. Romney leads in North Carolina and Missouri. Obama leads in Pennsylvania. New numbers from Wisconsin will be released at noon Eastern today.

Four years ago, after wrapping up the Democratic nomination, Obama led John McCain every single day during the month of June.
