From Rob Hotakainen in Washington:
Rep. Tom McClintock has raised $635,914 for the 2010 election cycle, more than any other California Republican on Capitol Hill.
Among Democrats, Sen. Barbara Boxer leads the pack, with $8.3 million.
That's according to the Center for Responsive Politics, which has assembled a list showing how much candidates have raised so far in each of the state's congressional districts and in the Senate race.
Boxer is seeking a fourth term, while McClintock is running for a second term.
