While I have similar doom and gloom feelings, I should point out
Biden is there for 4 years or 8 at worst, Obama was there for 8 and his main achievements are;
-Gay Marriage
-Killing Bin Laden
-Half assed Healthcare plan
-Fucking up school dinners for kids
-Drone attacks
-Botched Haiti recovery
-Benghazi
I don't like much of what the Biden campaign has in mind. He'll get some of the "b-but he didn't mean to do [insert thing everyone hates here]" that Obama got during his term, but he's also a rich old white dude. So he's not entirely immune.
I'm just saying, much as I struggle to believe it myself. Biden win won't mean end of America anymore than Trump winning meant LGBT conversion camps.
