Sherman and Schiff's races are seen as relatively safe, as they have more money and name recognition than their rivals — Mark Reed and John Colbert, respectively — and represent Democratic-leaning districts.
In 2009-10, Sherman says his campaign has given more than $746,000 to other Democrats. That includes $517,500 to the Democratic Congressional Campaign Committee and nearly $229,000 to candidates ranging from other House Democrats to California gubernatorial hopeful Jerry Brown.
"I'm proud of it," Sherman said, noting that a recent U.S. Supreme Court ruling made it easier for corporations and unions to pay for influential political ads that are not directly tied to candidates.
"Given the large amount of money given by corporations secretly, I felt I had to step forward," he said.
Sherman has also hosted fundraisers for others, including an August event for the Democratic Congressional Campaign Committee at the Western Diocese of the Armenian Apostolic Church in Burbank.
Schiff has given more than $163,000 to the Democratic Congressional Campaign Committee for the 2009-10 cycle, according to Federal Election Commission filings. Since he was first elected to Congress in 2000, records show Schiff has given more than $816,000 to the committee.
"Adam has always been supportive of other good candidates around the country," said Schiff campaign spokesman Parke Skelton. "The battle terrain is extraordinarily broad this year, and the needs for funding are major because there are so many seats in play."
