A group of New Yorkers will troop into a Manhattan courthouse in a week to perform the time-honored civic duty known as jury service.

But the case they may decide is like no other in American history — the first ever criminal trial of a former US president.

Donald Trump faces 34 counts of allegedly falsifying business records for paying “hush money” to porn star Stormy Daniels ahead of the 2016 election to cover up a sexual encounter.

Jury selection for “The People of the State of New York against Donald J. Trump” is to begin on 15 April and hundreds of residents of Manhattan have received summons to appear in court.

Twelve jurors and up to six alternates will be picked among them to hear the blockbuster case, which is expected to last up to six weeks.

The prospective jurors, randomly selected from public records, will fill out a detailed questionnaire and undergo a screening process known as “voir dire.”

Their verdict must be unanimous, and both prosecutors and Trump’s defense attorneys will be seeking to ferret out the political leanings of potential jurors to fashion a panel to their liking.

New Yorkers voted overwhelmingly for Democrats Hillary Clinton and Joe Biden in 2016 and 2020, respectively, and the Republican Trump is a polarizing figure in the Big Apple.

“Manhattan has a long history with Donald Trump,” said Leslie Ellis, a veteran jury consultant and founder of The Caissa Group.

“Not only just from his presidency and post his presidency but his time in real estate and business in New York before that.”

The 77-year-old Republican presidential candidate has repeatedly denounced the case as a “political witch hunt” brought by Democrats to derail his chances of recapturing the White House in November.

Trump’s lawyers have tried — and failed — to delay the trial on the grounds that the New York jury pool has been exposed to “huge amounts of biased and unfair media coverage.”

“Many of the potential jurors already wrongfully believe that President Trump is guilty,” they complained in a filing with Judge Juan Merchan, who will preside over the case.

District Attorney Alvin Bragg, who brought the charges against Trump, brushed aside the claim that he cannot get a fair shake in his hometown.

“Given the sheer size of New York County, it is absurd for defendant to assert that it will be impossible or even impractical to find a dozen fair and impartial jurors, plus alternates, among more than a million people,” Bragg said.

Empaneling a jury in the case does present particular challenges.

“On average in state court in New York you’re probably looking at a day or two of jury selection but this is not an average case,” Ellis said. “A lot will depend on how the judge conducts jury selection.”

Merchan has already ruled that the names of the jury members will be shielded from the public because of the “likelihood of bribery, jury tampering, or of physical injury or harassment.”

He has also warned Trump that if he violates a gag order prohibiting him from attacking witnesses, court staff or their families he could withhold the names of jurors from his lawyers.

Such a move would handicap Trump’s defense by limiting the amount of publicly available information his attorneys could research about a prospective juror.
