I would go all-in on trying to appeal to the Hispanic community, while trying to hold down suburban whites in places like Orange County. It can be done and there are efforts to do that, but it's not going to happen as long as Trump is the face of the party.
Until politics becomes less nationalized, you can't just revamp a state party in ways that contradict the national party in order to win state/local elections. The people's views of the national party will override all the others. Most of them won't make distinctions, which is why we've had a collapse in split ticket voting.
And even when voters split their tickets far more than today, it still didn't last forever. The South took a long time to transition from Democratic to Republican control even while they stopped voting Democratic at the presidential, but it still happened eventually. Nowadays it just happens much more quickly.
Yeah, but I'd reshape the national GOP in the same way. W won over 40% of Hispanics in 2004 and overwhelmingly won most suburbs. If we had the politics and rhetoric of W instead of Trump, those demographics would certainly be a lot better for Republicans than they are today.
How? That was over 14 years ago now, the country has changed big time since then. The people who live in those same suburbs aren't the same people anymore.
Plus this wouldn't be viable with the current Republican Party, if it was, then Jeb Bush would've won the 2016 GOP primary since he ran on an identical platform as GWB (he even had all the same people working for him). He lost in a landslide. Republican voters simply don't buy it anymore.
