WASHINGTON  Republicans enter the final six weeks of the election with a political wind at their back and opportunities for victory across the country, yet several state parties are at a severe financial disadvantage with Democrats, raising questions about whether Republicans can fully capitalize on a favorable climate.

In Iowa, Republicans finished August with just $34,819 in the bank, less than one-tenth what the Democrats there have. In Florida, Republicans have one-third less to spend. And in Missouri, Illinois and Indiana, where Republicans could be poised to win multiple races for Congress and the race for governor, the party is well behind its Democratic rivals.

At this point in previous campaign cycles, a large check has usually been in the mail from the Republican National Committee to help pay for the ground game. But this year, the party cannot afford to execute a robust voter turnout program, which could make a difference in tight races where Democrats hold a financial and organizational advantage.

“Will we be on par with Democrats on money?” said Matt Strawn, chairman of the Republican Party of Iowa. “Probably not, because we don’t control the White House. But will we have enough to get our voters out? I hope so.”
