The latest resistance plan against President Donald Trump's 2020 election campaign includes attempts in at least 25 states to pass a law that requires presidential candidates to release their tax returns to appear on the ballot, Axios reported.

President Trump is the only modern-day president to refuse to release his personal tax returns, so conceivably a law passed to require that could block him from the ballot. The issue with that trolling plan is no state has been able to officially pass a law requiring it.

Even deep blue California and New Jersey have vetoed the laws after it had passed both state chambers, but both Rhode Island and Maryland are currently working such a law in their state Houses after passing it in their Senate chambers, according to Axios.

Former Gov. Chris Christie, R-N.J., had called the attempt in his state a "transparent political stunt" in vetoing the law, while Gov. Jerry Brown, D-Calif., said it "sets a 'slippery slope' precedent for what individuals states could require of candidates," per Axios.

Such laws might wind up being battled in the Supreme Court, too, because they might not be constitutional. The top U.S. court has ruled in the past states nor the federal government can create new requirements for House or Senate candidates, AP reports, which likely would extend to the head of the executive branch, too.

Even if a deep blue state does pass the measure, it likely wouldn't stop President Trump anyway, since he would be unlikely to win that state in 2020 and still could win the election.
