George W. Bush is a born-again Protestant who says Jesus Christ is the philosopher who most influenced him. John McCain is a born-again Protestant who testifies that his faith helped him survive a POW camp. Al Gore is a born-again Protestant who says he frequently asks himself ``W.W.J.D?'' And Bill Bradley is a Protestant who, though he refuses to discuss his faith, belonged to the Fellowship of Christian Athletes and evangelized his basketball teammates.

The Protestant monopoly on this year's major presidential candidates may seem an aberration. John F. Kennedy's election supposedly cracked the religious wall in presidential politics, and the overt prejudice that barred Catholics, Jews and Mormons from national elective politics has disappeared.

Jews, who used to obsess about the first Jewish president, no longer think about the issue. Presidential campaigns have become as ecumenical as a Unitarian seder. Since JFK, candidates have been Mormon (Orrin Hatch), Jewish (Arlen Specter), Eastern Orthodox (Michael Dukakis) and Catholic (Ted and Bobby Kennedy, Bruce Babbitt, Pat Buchanan and-- surprise--Alan Keyes, among others).

The president on the TV show ``West Wing'' is even Catholic.

But life is not imitating art. Though non-Protestants comprise at least 35 percent of the American population, Kennedy remains the only one ever elected president. And of the 14 major party nominees since Kennedy's death, only Michael Dukakis was not a Protestant. (Barry Goldwater's father was Jewish, though Goldwater was not.) And there are good reasons to believe that the Protestant monopoly will persist.

America has not returned to the bad old days of know-nothingism and anti-Semitism. The Protestant monopoly no longer stems from prejudice. Americans insist they would vote for a presidential candidate of almost any religious background. In 1937, 46 percent said they would vote for a Jewish presidential candidate, and 47 percent said they wouldn't. In 1999, 92 percent said they would vote for a Jew, and only 6 percent wouldn't. In 1958, 27 percent of Americans said they would not vote for a Catholic. In 1999, only 4 percent said they wouldn't.

Though folks probably pretend to be more tolerant than they are, the virulent anti-Catholicism that cost Kennedy 2 million votes has vanished, as has most anti-Semitism. No one would dream of hinting that a Catholic president would take orders from the pope, as some did in 1960. Mario Cuomo says he ``never even considered the possibility'' of anti-Catholic prejudice when he was pondering a presidential run.

Recent non-Protestant candidates didn't fail because of religion. Hatch was dreary. Specter was a pro-choice Republican in a pro-life party. Ted Kennedy never recovered from Chappaquiddick. Bobby Kennedy was murdered. Buchanan was too vitriolic.

The free pass does not extend to all religions. Seventeen percent of Americans won't vote for a Mormon, the same as in 1967, the last time Gallup surveyed about Mormons. Gallup does not poll about Islam or other religions, probably because not even optimists believe a Muslim could be elected president now.

As for atheists, forget it. Only 49 percent of Americans would vote for an atheist presidential candidate compared to 59 percent who would vote for a gay one.

If prejudice isn't blocking a Catholic or Jewish presidency, why hasn't there been one lately?

First, evangelicals are a huge obstacle to a non-Protestant Republican presidency. Evangelical Protestants comprise one-quarter of the population, they favor Republicans by 2-to-1, and they are concentrated in the Southern states that are the Republican base.

``Given the strength of evangelicals and the concentration of the party in the South, it would be very difficult for a Catholic to get the Republican nomination for president,'' says Catholic University politics professor John White.

This constituency is one reason why Bush and not a Northern Catholic such as John Engler of Michigan, Tommy Thompson of Wisconsin, George Pataki of New York, or Tom Ridge of Pennsylvania is the Republican governor running for president.

Demography also damages the presidential prospects of Catholic and Jewish Democrats. Jews and Catholics populate the Northeast, but since the Dukakis debacle, the Democratic establishment has all but abandoned Northeasterners as serious presidential candidates, concluding that they are too liberal to succeed nationwide. This eliminates the most promising Jews and Catholics from presidential consideration.

``The two easiest groups to elect president,'' says University of California, San Diego professor Sam Popkin, ``are Northeastern Republicans and border state Democrats''--lefty Republicans and righty Democrats virtually none of whom are Catholic or Jewish.

Abortion undermines Catholic presidential candidates. A Catholic candidate's abortion position, no matter what it is, would incite far more anger than the same position taken by a non-Catholic. Most Catholics are Democrats and are pro-life, but a pro-lifer can't win the Democratic nomination. (Witness the ostracism of former Pennsylvania Gov. Bob Casey.) And a Democratic Catholic candidate who was pro-choice would be at odds with a noisy and powerful church hierarchy and might lose some of the Catholic vote on which Democrats depend.
