Republicans hold a clear fundraising edge as the midterm elections enter the final stretch, even as they trail Democrats in national and swing-district polling. According to Sina Finance, Federal Election Commission filings show Republican national committees held about $233.4 million in cash at the end of September, nearly twice the $130.4 million held by their Democratic counterparts.

According to Sina Finance, MAGA Inc., Donald Trump's main super PAC, had $415.8 million in funds, while two Trump-linked committees, Never Back Down PAC and Secure and Affordable PAC, had reserved at least $126 million for campaign advertising. AdImpact data showed Republicans and their allies planned about $888 million in advertising through Election Day, compared with about $666 million for Democrats and their allies.

The report said Democrats still held stronger cash reserves in some key swing-district races. It also noted that Republicans must defend 16 of the 21 House swing seats rated by The Cook Political Report and 6 of the 9 core Senate battleground seats.

At the committee level, the Republican National Committee had $125.6 million in cash at the end of August, while the Democratic National Committee had $16.9 million and $17.6 million in debt. The Republican National Committee's cash was more than seven times the Democratic National Committee's.

According to Sina Finance, the U.S. Supreme Court ruled in June to loosen limits on coordinated campaign spending between parties and their candidates, increasing the influence of party funds. The Republican National Congressional Committee also held a cash lead over the Democratic Congressional Campaign Committee, while the Democratic Senatorial Campaign Committee had more cash than the National Republican Senatorial Committee in early September.
