People like Trump and Sanders for one big reason that they both have in common, they aren't being bribed like every other candidate. Like them or hate them, people are just sick of having politicians begging rich people for money. As for the general election, its a little early to know who's winnable.
Nonsense.
No one is being 'bribed.'
Trump supporters are for the most part naïve, sophomoric libertarian/TPM reactionaries hostile to sound, responsible governance, who perceive Trump as a way to 'shake up the system,' and poke a petulant finger into the collective eye of 'the establishment.'
Sanders supporters are the disaffected liberal fringe relegated to the political backseat after 1988; they get play-time with Sanders until the adults take control of the Party just before the primaries.
