Could the Vote Be Contested Again? 5 Threats to a Smooth Election.

For the past four years, Donald J. Trump has been proclaiming the American electoral process “rigged,” decrying events that displease him as “election interference” and laying the groundwork to contest another loss at the polls.

It follows the playbook from his loss in 2020, when the former president weaponized disinformation and exploited perceived weak points or vagueness in election law in an attempt to overturn results.

At the same time, lawmakers and election officials have been trying to shore up the electoral system against another potential attempt to subvert a presidential election. Federal laws regarding the Electoral College were changed. There is stronger case law to knock down specious legal claims, and Mr. Trump is no longer sitting in the Oval Office with the levers of government in his grasp.

But even with a national effort to reinforce the country’s democratic institutions, a smooth path to picking the next president still requires the good faith buy-in of its citizens, candidates and political parties.

Already, more than 187 election-related lawsuits have been filed, including at least 116 seeking some restrictions to voting and 68 filed by those seeking to expand or protect voting, according to data from Democracy Docket, a Democratic-aligned group that tracks election cases. The cases represent an extraordinary inundation of litigation before the election.
