Of course it's legal. What is a fiction is the Democratic Party actually cares about the primaries. They haven't run a clean one such 2012. What is the problem? That they tried to hide Biden's cognitive decline by not meeting with the press, Congressional leaders, and the public for a full year. Look it up. Unless it was during his limited hours where he could have a semblance of normality.
And your attempt to deflect it shows how worried you are about this truth. You know it is the truth. And you are willing to compromise the recognized proper path to the WH, pretty much democracy itself, all to supposedly save it.
Of course it isn't the most important thing in my life, but considering you posting history, Trump is clearly to you. And that is just so pathetic. I enjoy watching partisans like yourself get twisted up in knots. You are clearly so emotional about Trump. He is the bad girlfriend you hate. So much so ypu can't see how toxic the Dems are as well. You think they are above criticism.
No one is.
