Yes. WE know their history, but the public, maybe too young to remember, will have to be reminded of what you say early and often.
In reality the Republican Party won't BECOME reversalists. BUT they will SELL that to gain votes.
That reversalist stance will be the most difficult for Democrats to message on, just because they've been in reactive mode for 40 years, fighting off Republican labels. Reversalists will try to peel off Democrats and "independents" (who've registered in big numbers, according to Pew) by selling some softer version of "socialism," called "social capitalism" (Rubio's working on speeches to explain that right now, I bet).
If Republicans actually remain true to their older goals (small govt, conservative spending, lol stuff) we'll have to slam that hard and call reversalist ideas 'fake news' and trumptrashtalk, just to cast doubt on both their real history and their credibility ever since Obama.
They've lost all their old Republican identity by tossing the 2020 party platform, and we must stay out ahead of any of their messaging attempts, call out what they actually DO. Overall, slam their platform building with "Why would Americans go for Democratic Lite when they already have the real thing!"
Taking control of defining our opponents is what we've not been as good at as they for over 40 years. So now's our chance. To stay in power now, we must DO more than talk. That's what the big turnouts have been wanting since Obama.
Thank you for checking these scenarios out, and thanks for your post.
