Sorry for not responding to the concerns of Representatives Cao and MB, but in the text, the chair of the party who the candidate would have to approve the candidates being listed with the names of the party on the ballot, and a candidate endorsed by the party would have to ask the chair of the endorsing party to allow the SOFE to list them on the ballot.
…in other words, we have at least three people to loop in, possibly more, for each such decision made?
I will note that my concern really hasn't been assuaged here, and while I am not a fan of killing bills that could still be worked on, this entire idea seems impractical and – as Yankee mentioned – has been tried before without much success.
