MANCHESTER, N.H. (AP) — Armed with a fresh slate of primary victories, Mitt Romney is urging Americans to "hold on a little longer."

The former Massachusetts governor tells New Hampshire supporters that Tuesday marks the beginning of a new campaign focused solely on President Barack Obama. He accuses the Democratic president of "false promises and weak leadership."

Romney spoke Tuesday night as he scored Republican primary victories in Connecticut, Rhode Island, Delaware and Pennsylvania in the first contests since Rick Santorum suspended his campaign. New York was expected to follow.

Romney delivered his remarks to a national television audience from Manchester, N.H., where he won his first primary of the campaign. The state is also expected to be a battleground in the fall campaign for the White House.
