I wonder what she saw in the Epstein files? It seems like this is what put her over the edge. Same with Boebert.
She'd probably have had some talks about Epstein and the "files" with Massie. Evidently they're friends. While I'm sure he'd have shared at least some of what he knew, I'm not sure how much that would have been. I think Bobo followed MTG into all this; in the beginning, the Republican rebels were MTG and Nancy Mace.
I also think MTG's "battered wife" remark suggests she has some experience of sexual abuse that she hasn't told us about. If so, being ignored by her former hero on that issue would be even more galling. I don't think she has special info about Trump's activities with Epstein that turned her against Trump.
It seems possible she--like many a scorned woman--believes Trump will see the error of his ways, apologize, and once again support her. But I don't think she should count on that.
So far, most people seem to think that at least for now, Marge will return to her "sweet little district" to play with her grandchildren for a while. Or, perhaps more reasonably, to go on a speaking tour while working on a book. I dunno about that. On MSNOW, Cornell Belcher just said he thinks she'll run for governor in Georgia. That wouldn't surprise me at all, though I don't know if she has a chance of winning.
