Please allow me to preface this post by saying I have donated to and voted for Sanders already. If you feel so inclined, you can sift through my post history on /r/politics to find plenty of proof and plenty of posts critical of Hillary. That said:

1) Bernie has outspent Hillary in almost every state lately that he's lost. Experience and name recognition are hard to put a price on.

2) Bernie is still losing without unpledged delegates and the lead is only widening because he is underperforming almost every demographic besides whites aged 20-29. As for superdelegates, they exist to stop a Trump situation from happening.in the Democratic party. Sanders himself is a superdelegate for the Democratic Party, for the record.

3) Bernie is losing because he refused to go on the offensive until if was too late and because he has refused to brush up on his foreign policy and it has been glaringly obvious in debates, which doesn't help the public's opinion that he's a one-issue candidate.

4) Regardless of who gets the nomination, they will need a House and Senate willing to work with them. Hillary has been going out of her way to campaign for down-ticket Democrats to try to ensure this happens. One of my biggest frustrations and disappointments with Bernie is that he has only done so with 3 or 4 candidates that support him. Even if he were to win the presidency, he won't get half of his agenda done if the GOP controls the House and Senate.

5) If you're willing to risk SC decisions that set dangerous precedents that could potentially roll back the last 8 years of progress we've had under Obama and possibly hurt the rights of minority groups or privacy issues just to send a "fuck you" to Clinton, feel free. I'm not willing to do so in good conscience.
