WASHINGTON (AP) — Political parties and their committees faced a Monday deadline to disclose how much cash each raised last month and how much they had on hand as October began.

Democrats’ campaign committee for House races picked up $16.7 million in September despite long odds of winning a majority — surpassing both parties’ campaign arms focused on the Senate, which is very much in play. If Republicans net six Senate seats and win handily as expected in the House, they will control both chambers in Congress for the final two years of President Barack Obama’s term.
