Well, I went through that surprisingly quickly, and resisted the temptation to only vote for dashed lines.
Tulsi over Joe. Those two are probably the most suited by temperament and experience to being Commander-in-Chief. Tulsi isn’t likely to support frivolous foreign engagements, whereas Joe is. Tulsi, easily. [I see I’m the first to make that choice. Well, I’m still right.]
Beto over John Delaney. Yeah, I’ll go for the punk rocker over the banker. They’re both nice guys, they’re both too corporate, but Beto seems very sensitive to race & immigration issues.
Bernie over Amy. Yeah, should’ve signed onto Medicare for All, Amy.
Inslee over Booker. Environmentalist beats whatever kind of corrupt corporate tool Booker is.
Bullock over Buttigieg. Governor beats mayor. Also, while neither of them could get through the actual primary, Bullock probably really would win over some moderates and swing voters in a general.
That said, Yang over Hicklooper. Governor beats salesman; but as ridiculous as Yang is, I still picked him over Hickenlooper. Vision counts for something, and apparently Hick’s been insulting the “socialist” wing. Drop out, John.
Gillibrand over Harris. This may be an unpopular choice. [Oh, look, I am the first to make this choice, too.] But I think Gillibrand is a more sympathetic figure than Harris. Ymmv.
Warren over Castro. Warren over everybody, let’s be serious.
