Johnson/Weld ticket. Hope they drain enough from the Repubs so Hillary wins and I get to keep my ACA health coverage.
Gary Johnson has said that he is closer to Bernie Sanders politically than any of the Republican candidates.
Bernie is a socialist with mostly tolerant social policies. They differ on fiscal policy, but Bernie and Johnson is close to Sanders on most social tolerance issues.
Trump is a loose cannon, he's all over the place. But he's actually less of a warmonger and less of a corporate shill than Hillary (I know, it's weird, but at least Trump isn't holding out his hand to Goldman Sachs all the time like Hillary does).
Politically, Hillary is a corporatist, middle of the road, warmongering Republican. She's been VERY slow to warm to tolerance issues like gay rights (she only does so once she's sure the vast majority are going that way).
She and Johnson would disagree on a wide variety of social issues, and on Foreign policy, Gary Johnson is a polar opposite of Hillary Clinton, who essentially agrees with the entire Bush/Cheney "shoot first" version of foreign policy.
So Johnson is more likely to pull progressives and pacifists (who rightly despise Hillary) from the Dem party than pulling Republicans from whatever the Hell Trump (he's got an "R" next to his name on the ballot, but he doesn't really seem to stand for anything).
