Senate Republicans’ strangely uneven spending map

Republicans are spending more money in a single state, Pennsylvania , than in Michigan , Wisconsin and Arizona combined.

GOP super PACs and mega-donors are putting more money into former Gov. Larry Hogan ’s uphill Senate bid in Maryland than in blue-leaning Maryland .

In Arizona , Rep. Ruben Gallego alone is spending more than all the Republican advertisers, including outside groups, combined.

Outside spending has propelled pro-McCormick advertising in the state to a massive $113 million from Labor Day to Election Day .

Democrats are spending a collective $81.6 million during that period, with $21 million of that coming from Sen. Casey ’s campaign.

Republicans know McCormick will need every possible minute of advertising to get his message out in Pennsylvania .

Tim Sheehy in Montana and former Rep. Mike Rogers in Michigan also have dedicated outside groups supporting their Senate bids. That allows donors to cut large checks to help a specific candidate, but it also means less control for groups like the Senate Leadership Fund , which is meant to be a party clearinghouse and can direct resources more strategically across the country. "The decentralization of Republican fundraising is a real thing that is happening, and it will happen even more next cycle," said one GOP strategist involved in Senate races, granted anonymity to speak candidly. "It incentivizes candidates to build their own ecosystems.".
