Democrats who registered as Republicans to vote in the Republican primaries tend to vote for Republican candidates who lose in November.
IF your guy is going to win the primary in your state, Cruz or Trump, (or the other way around) then vote Bernie to keep the Rat fight going.
Even if the other guy is winning, as I said I support Cruz but would vote Trump, then still vote Bernie. Just keep the Rats at it, make them get nasty! Hey, it doesn`t hurt to get the Rats all riled up at the 'other one' and maybe make Bernie (or the HildaBeast) run as an Independent.
Like Ronald Reagan lost, you mean ? /s
