"Forced to" may have been a poor choice of words on my part.and i hope that succeeds as well. i'm sorry if i mis-read your intent in your post (very possible), but i don't think that Castro can "force" them to do what we were discussing. apologies offered.
At any rate, several states that DJT won in both 2016 and 2020 are seeing lawsuits challenging his eligibility by a Republican Presidential "hopeful" (And I use that term loosely because he seems to know he has no chance of winning.). Meaning they will have to make a decision on whether or not to bar Trump from running instead of just ignoring the issue entirely as I am sure they would prefer.
From a politician's stand point, "Why have that discussion if we don't need to?" Well, now they need to and it will be public record. And that can be used against whomever in the future. To what ends remains to be seen. But it will come back to bite someone in the ass no matter how it ends.
And I think that's kind of the point of the lawsuits as well as barring Trump.
