Recent Republican polling in Michigan revealed just how nettlesome President Joe Biden’s political vulnerability can be for House Democrats as they struggle to defend their majority.

In the new 7th Congressional District, late November polling by the GOP firm Cygnal found Biden’s approval at an abysmal 40%, with 56% disapproving of the job he is doing as president. In the same survey, Republicans led the generic ballot, gauging which party voters would prefer reign in Congress, by a whopping 10 percentage points, 51% to 41%. That could spell trouble for second-term Rep. Elissa Slotkin in 2022.
