Faithless electors are members of the Electoral College who do not vote for their party's designated candidate. Since the founding of the Electoral College, this has happened 157 times. The Supreme Court ruled that states may empower political parties to require formal pledges from presidential electors to vote as expected, but 21 states still don't require members of the Electoral College to do so.
Even states that have been more proactive on the issue of faithless electors have dealt with them rather gently, charging them with a misdemeanor at most, and subjecting them to a small fine. States that have laws against faithless electors include South Carolina, North Carolina, Virginia, California, Oklahoma, Michigan and Vermont.
"But that situation is a different because the Electoral College was established by the Constitution; political conventions were not," Potter said.
"I suspect a state can bind people at the convention on the first ballot, forcing them to vote as pledged, but how do you pursue the case n court if they don't? And how do you get the remedy in time? We've never found that out," Potter said. "We've never been in that situation."
Of course, after the first ballot at the convention, most states say the delegate is free to vote for whoever they want. In theory, all pledges are off.
"But then again, it depends on what the party has done with its rules," Potter said. "You can be in the bizarre situation where there is only one candidate who has qualified by winning eight states under the current rules, but a majority of the convention doesn't want to vote for him."
Potter imagined a situation where enough delegates abstain so that the single qualifying candidate doesn't get enough votes to secure the nomination, setting the stage for a second ballot.
"But if you're in the group that wants to bring that candidate down and support somebody else, you've still have to go through the whole process of changing the rules to get the other person nominated on the second ballot," he said.
The fact of the matter, Potter said, is "you can look down the road and come up with all kinds of scenarios that suggest this could get very messy. Whether we get there, who knows?"
But the almost endless possibilities raise other questions.
For instance, if a candidate for argument's sake, Donald Trump was denied the Republican party's nomination and truly believed he was entitled to it, couldn't he sue to either have it awarded to him or to prevent someone else from, as he would see it, "run in his place."
"Sure, he could," Potter said. "Anyone can file a lawsuit. But any chance of success would depend on the specifics."
"If he could argue that he was cheated because the party broke its own rules and failed to follow its lawful procedures, then he'd have a better shot at it. That said, I still think the odds of any court intervening in that situation, and ordering the party to basically go back and do it over, are exceedingly slim. I think the courts would stay out of it."
"In the meantime, the party nominee would go ahead and campaign, assuming the party was going to win ... but there would be an ongoing lawsuit in court," Potter said.
Then of course there's the possibility of Trump opting out of the potential brokered convention and running as an independent.
"But that's pretty murky," Potter said.
"Some states have very early deadlines for filing as an independent," he explained. "For instance, the Texas deadline is May 9, and in order to file, you actually have to get 79,000 signatures, which would be an enormous effort.
"If someone were hoping to get on the Texas ballot this year, they'd be collecting signatures now, and Trump can't do that because he doesn't know yet that he'd be forced to run as an independent," Potter said.
"So again, speaking hypothetically when he knows for certain that the party is going to deny him the nomination is critically important to his deciding whether to make an independent run," he continued. "If it's in Cleveland, it's really too late. However, if he decides in June that the odds are stacked against him, that he's not going to get a clear majority on the first ballot and that as a result, he's not going to get the nomination, then he would still have time to get on a number of state ballots.
"Some states have very low thresholds for qualifying to be on the ballot; others, very high thresholds. But he could gather signatures and get on some. Or, he could become the nominee of parties, third or fourth parties, that already exist in various states, like the Conservative Party in New York ... or the Libertarian Party elsewhere.
"Not that I think they would have him, but he could look around and see if there are parties that would put him on as their nominee and that would allow him to skip the petition process," Potter said.
In short, if Trump were to try an independent run, he'd be facing hurdles that grow more insurmountable by the day.
Potter said those very hurdles were something that figured in Michael Bloomberg's thinking even in January and early February.
"The advice he was given was that if he was going to run, even with his billions, he would still have to be running by mid-March because of the Texas filing deadline. That's one reason I also don't see anyone else trying to run as an independent," he said.
"It takes money, of course. So it's much more convenient to contemplate if you're a billionaire and much harder if you are not but there are all kind of other issues to deal with. That's why I don't put much stock in it when I hear that political consultants in Florida and elsewhere are advising wealthy Republicans on how to mount an independent candidacy."
"I say, 'Well, who's your candidate going to be? You don't have a candidate.' Presumably, it's not going to be someone like Rubio who has already lost a bunch of primaries and no one is enthusiastic about," he said.
"So ... who? [Mitt] Romney? To back someone for such a run, you have to have a pretty well-known name who is ready to step in, and my guess is most of those well-known names want to wait to see what's going to happen at the convention ... and by then, as I said, I think it's too late to get on the ballots."
Even if Trump were to get on a number of ballots, at this late date, Potter said it would be unlikely that he could get on enough to win the presidency.
"But he could certainly get on enough ballots to cause enormous trouble for the Republican nominee. I mean, it doesn't take being on many ballots in what ought to be Republican states to knock the bottom out of a Republican candidacy," Potter said.
