The future for the GOP is clearly a multiracial working class coalition, so I voted #2 and #4. This is easier said than done, though, and will eventually entail them dropping both their hard right economic positions and racial dog-whistling, which will be hard for many in the party to do.
The electoral results of the past few years have been glorious for this. It's so exciting to see all the fiscal conservatives who told the other parts of the right to shut up for the sake of electability getting told that they are the ones who need to tone it down.
Soon the GOP will be more economically left-wing than the Dems and the force to counter the neolibs. They wouldn't have to change colours, they're already red. I suspect we're seeing the next big re-alignment soon. They should just be socialist without ever using the word, basically like a mix of populist socially conservative social democrats or populist socially conservative christian democrats (while staying anti-war and anti-globalist), but be less childish and more accepting of blacks, hispanics and LGTBQ's.
Anyway, Trump's four years was necessary to destroy the neocons, a greater force of evil than trumpism. And i'm glad that W. Bush is still alive to see what is happening now.
