1. MAGA types hate Rona McDaniel. She isn't viewed as one of them.
2. As the Venn diagram of "Republican", "Conservative" and "MAGA" condense to a single circle, "RINOs" like Rona are going to be hard up, especially if they are blacklisted everywhere outside of that. Probably deserved, leopards eating faces, etc.... but...
3. If someone formerly enabled Trump and MAGA but now feels compelled to work against them, it is in my family's best interests for them to find a place to do that. I have no idea if that is what Rona was going to do, but we are in an immediate existential crisis for the country as we have known it. If she's willing to help prevent a complete Trump takeover and establishment of a MAGA federal government, then I don't care what she did two, four, six years ago. I want her help to keep Trump out of the White House now.
4. A whole lot of people benefit from citizen outrage our country's internal strife, and they are not all part of the MAGA movement. Media across the political spectrum has a particularly strong profit motive in promoting war vs peace.
