I found this extremely interesting but one thing I think is important to remember: it's possible that Republicans will take down Trump in 2020 (or sooner), but it's more likely that non-Republicans will. Mobilizing and organizing support among the left and independents would be more than enough to win a Presidential or any other election in the US outside of DEEPLY Republican areas. Looking forward opportunities to win over tepid Trump supporters is one strategy, but don't let anyone convince you it's the only strategy (or even the best one).
