The Democratic Congressional Campaign Committee, House Democrats' official campaign arm, had reserved more than $8 million on broadcast and cable TV in the state as of Sept. 21, compared with $1.6 million last cycle, spokeswoman Jennifer Crider said.
In that same period, Republicans had reserved $7.6 million for five California races, $5.4 million for the Sacramento market alone.
Super PACs from both sides already had spent nearly $3 million on California's congressional races, ranking the state behind only Texas and Indiana for independent expenditures for state congressional contests through the end of June, according to MapLight, a nonpartisan group that analyzes money's role in politics.
