For me? Easy. Is aw nothing in Bernie Sanders, despite how much I like him an agree with his policies, that indicated he could do the job of President. I consider a presidential campaign an extended job interview, and the point of us as voters is to pick the best candidate for the job, not the candidate we like the most or the one we agree with the most. Bernie is a very principled, decent man. He would also have been a train wreck as a President because decency and ideological purity are not qualifiers for the office, rather the reverse.
Bernie is a good man, but not a good candidate for the job.
Hillary is a god damn ball busting badass powered by nuclear fuel rods, and that’s who I want on the oval office.
