If Biden were a private person this would be sad. He is the fucking president. He cannot be allowed to stay in office. You are voting for [unknown] if you vote for Biden. You are voting for the end of democracy, because you are explicitely telling the Democratic party that it doesn't matter who they put up as a candidate. You are explicitly saying "I won't hold anyone accountable because it is clear that Biden is not running the White House."

There are other choices than Biden and Trump. Jill Stein is the only semi-major party candidate against our foreign wars. If the Greens can get to 5%, they get matching funds.

Even before that threshold, if the Dems and Repubs know they cannot win without Green support, they become kingmakers as well as having real legislative leverage.
