"I think that's wishful thinking and not particularly realistic based on my encounters with the MAGAs."

Not to put words in his/her mouth, but I think GG is referring mainly to (ill informed?) independents who voted for Trump the first time, maybe told a bunch of their friends, and may still say to pollsters they are going to vote for Trump, but aren't really going to.

You're right about the MAGAs though. They are fully under the influence of the cultist kool-aid and would never in a million years vote for anyone but Trump. Changing their minds cannot be part of the strategy. That will never happen.
