WASHINGTON - Jeb Bush kept his struggling presidential campaign afloat with a $250,000 personal loan - barely enough to keep the campaign from plunging into debt.

New campaign finance documents show the former Florida governor raised about $1 million in February, which was to be his final month as a Republican candidate.

Documents show his campaign wrapped up with $13,127 more in cash than debts. He left the race Feb. 20 after a fourth-place finish in South Carolina.

New Jersey Gov. Chris Christie's report shows he raised about $420,000 in February. The Republican suspended his campaign Feb. 9, after the New Hampshire primary. Christie's campaign ended with roughly $200,000 more in debts than available cash.

Other candidates - current and former - are due to file reports by midnight Sunday.
