Scoop: GOP doubling down in toss-up Michigan Senate race

• SLF, linked to Senate Minority Leader Mitch McConnell, only started going into Michigan this month, with a $22.5 million investment announced Sept. 30th.
• They have focused their spending in Montana, Ohio and Pennsylvania.

Zoom in: Recent polling on the Michigan Senate race has been split. The most bearish news has come from SLF's own internals, which has Rogers down by 8 percentage points this month, as Politico reported.

• Internal polling of likely voters for the Rogers campaign has him down by one, according to a memo obtained by Axios.
• Polling by the Republican Senate campaign arm and public polling by Quinnipiac are even more hopeful for Republicans. They show Rogers tied with Democratic nominee Rep. Elissa Slotkin (D-Mich.).

What to watch: In addition to the top GOP issues of the economy and immigration, Republicans see the Biden administration's electric vehicle (EV) policies as particularly potent in the top car manufacturing state.

• "Michiganders don't like that Elissa Slotkin has consistently voted for Joe Biden and Kamala Harris' green energy agenda. These voters are looking for a change from the Democrat status quo," SLF President and CEO Steven Law told Axios in a statement.
