Republican U.S. House candidate Carl DeMaio raised more than $370,000 during the final three months of 2013, his campaign will announce later Wednesday. The strong total enabled him to build a seven-figure campaign account for his effort to unseat Rep. Scott Peters (D-Calif.), one of the most vulnerable Democrats running for reelection.

Most of the money DeMaio raised last year ($1.2 million) came from individual contributors. About $70,000 came from political action committees. He ended the year with $1 million in the bank.

A former San Diego city councilman, DeMaio lost a competitive race for mayor in 2012 to Democrat Bob Filner. Filner resigned from office last year amid sexual harassment allegations and DeMaio considered making another bid for the city's top job before announcing in September that he would continue his campaign for the House.

Top House GOP leaders have signaled support for DeMaio's campaign by donating money. DeMaio, who is openly gay, has called on his party to focus less on social issues and more on fiscal matters.

Peters has not released his fourth-quarter totals yet. He had about $806,000 in the bank at the end of the third quarter.

Here are the other notable fourth-quarter totals announced Wednesday:

* Sen. Mary Landrieu (D-La.) raised nearly $1.4 million and ended 2013 with about $6.4 million in the bank. Republican Rep. Bill Cassidy, Landrieu's main opponent, also had a good quarter. He hauled in more than $1 million and finished with $4.2 million in the bank.

* Rep. Mike Simpson (R-Idaho) raised more than $430,000 and ended the year with more than $760,000 in the bank. Simpson faces a primary challenge from attorney Bryan Smith, who is backed by the Club for Growth.

* A super PAC backing Sen. David Vitter (R-La.) — and potentially his 2015 candidacy for governor — raised $1.5 million throughout all of 2013.

* Democrat John Lewis raised more than $200,000 in his bid for Montana's at-large congressional seat. The former Max Baucus aide ended the year with about $319,000 in the bank.
