I hope that Bernie is capable of being shallow.

Whether you like it or not, presidential politics is overwhelmingly determined on image - not substance. We already know Bernie Sanders has substance. What remains to be seen is whether he can translate the substance of his views into a larger, shallower, more broadly-applicable image that convinces people who don't know very much that he is their candidate.

If he is serious, then learning how to be shallow will be the subject of his study for the campaign. If his only intent is to "steer the debate," then he will fail: Hillary Clinton will not learn anything, no matter what. She has proven that too many times over now. She learns nothing. At most he would make her use some unfamiliar vocabulary for a while before reverting to form. So I hope that his candidacy is serious - that he intends to be President of the United States.

If so, he needs to quickly start learning how not to be so genuine. How to instead spread his substance more thinly, into more shallow threads that normal, uninformed people can relate to. That is the reality of politics in this country. If he plays the self-gratifying game of running the campaign he wants rather than the campaign we need, then nothing will happen. He will be just another lightweight in a long list of them.

Bernie, be the candidate we need. Whatever you've been before, whatever you want to be, forget that and be what we need. Don't be another lightweight making symbolic points. Fight so hard and so deeply you sicken yourself. Let people into your campaign whose soulless mercenary hearts make you sick.

This is what it is. Don't be our ennobling loss. Rise to the day. You're all we've got. Don't repeat the stupidities of history, and don't embarrass us by being a new Ralph Nader.

Win. That is all we require of you.
