Republican-aligned outside groups are buying airtime at close to five times the Democratic rate with both sides heating up in Michigan. ​

In the latest reporting window, GOP-sponsored filings totaled $18.9 million across 278 filings, compared with $3.8 million across 144 Democratic filings.

Michigan is the clearest contest. It is the only state where both parties are spending heavily: $6.8 million in net buys, the most of any state. Its Senate race is rated Lean Democratic. Florida ranks second at $6 million, almost all of it from Republican groups. Texas ($2.4 million) and Pennsylvania ($2.1 million) follow.

Three groups drive the Republican total. No Going Back PAC led all spenders with $9.8 million, nearly half of it ($4.4 million) in Florida, plus $1.8 million in Texas and $1.2 million in Michigan. Congressional Leadership Fund, the House GOP’s main super PAC, added $7.3 million, led by Michigan ($3.2 million) and Pennsylvania ($2.3 million). Senate Leadership Fund put $1.7 million into Senate contests, mostly Nebraska ($623,000) and Ohio ($609,000).

Democrats are concentrating on fewer states. House Majority PAC spent $2.2 million, almost two-thirds of it ($1.4 million) in Michigan. WinSenate reported $1.6 million, with $1 million in Michigan and smaller amounts in Kansas, Maine, Iowa and Ohio.

Some states saw net reductions. New Jersey dropped the most (–$530,000), tied to the Lean Democratic 7th District. California (–$510,000), Georgia (–$266,000), New York (–$195,000) and New Hampshire (–$25,000) also declined.

Several major groups reported no filings in this window: MAGA Inc., One Nation, American Action Network and House Majority Forward.

What it means: Republicans have a large spending advantage and are spreading it across a wide map. Democrats are putting most of their smaller budget into Michigan. How Michigan goes will show whether that focus pays off against a much larger opponent.
