That's not bipartisan, that's third party. They're talking of creating a progressive left-of-centre party, but I guess don't want to say so,
The structure is specifically to avoid the necessity of bipartisanship, which is good, since the last qualifier would hardly be possible otherwise. Another tell is the second to last qualifier. Neither party is going to go along with that, necessitating an independent candidate in nearly every race, with perhaps the occasional Dem hold-out
Put 500+ candidates together under one website with unified policy and you have a party, not a bipartisan effort.
Good for them, hope they do it. Winning 10% of the races out of the gate will change the face of US politics for the better, faster than most any other thing to be done.
