MTG has a higher chance of being the VP than you think

She would sink the ticket harder than Palin did. I know McCain was dead in the water regardless of who he picked as VP, but this would tank any chance Trump has.

I don't think she dooms him. She isn't good electorally but at worst it moves the election from Lean Trump to Lean Biden. Trump is already associated with her anyway.

She compromises any rationality a Trump curious voter might come up with to vote for him. There were voters in 2016 who probably saw Pence as a reasonable voice in Trump's citcle. Greene would not be given that benefit of the doubt.

MTG might be a worse pick than Palin in terms of scaring away independents.

She is also somehow an even bigger attention whore than her. Maybe even Trump when it comes down to it. If anything, that's the only reason he wouldn't pick her would be her upstaging him more so than the negative press she'll garner.
