It makes very little difference whether MTG "wins." While she remains the face of her party, her party loses in purple states. Tactically, nothing could be better for the Dems than for this silly woman to speak for her bankrupt party.
Ditto, Trump's coming acquittal. Every purple state senator who votes for acquittal will run against a side-by-side ad showing a coffin in the Rotunda and him or her voting "nay" on conviction.
