OP is pretty condescending. There's a lot on the line for a lot of people this time, especially up against a candidate like Donald Trump. Any uptick in his chances brings him that closer to the presidency, and it's literally a terrifying prospect.
Add to that the fact that some of us are
genuinely excited about Hillary Clinton (how shocking!
), and it's not hard to see how the stakes could be doubly raised. I won't stop panicking until November 8th. Let the panic spread and spread until she's won outright. That's what I say.
Also, let's dispense with the sh-t about "not needing" even a majority of the battlegrounds. That may be technically true, but for those of us who actually have hopes for what comes beyond November, running up the margin is important. She still has the power to do it, so I refuse to count that possibility out.
