What’s scarier?

Hillary Clinton’s huge “superdelegate” edge?

Or Donald Trump’s rapidly growing ranks of stupor-delegates?

And this related, rising prospect — or is it already a sure thing? — sounds even scarier:

A Clinton vs. Trump general-election battle of the bombastic bullies.

Clinton has a large polling lead going into Saturday’s South Carolina Democratic primary, mainly because she holds a wide advantage over Bernie Sanders among black voters.

But why?

And why do so many self-billed conservatives in our state (and beyond) back Trump, now on a three-GOP contest winning streak after rolling in our state’s primary on Saturday and the Nevada caucuses on Tuesday night?

That’s four in a row for Trump if you buy his claim to being the rightful winner of the Iowa caucuses. He demanded — but didn’t get — a “do-over” there after decrying what he saw as Ted Cruz’ underhanded tactics.

In the Las Vegas afterglow on Tuesday night, the New York City billionaire braggart still sounded sore at the sanctimonious Texas senator, telling triumphant Trumpians:

“I’ve met much tougher people than Ted Cruz. He is like a baby compared to some of the people I have to deal with. He is like a little baby — soft, weak, little baby by comparison.”

Trump didn’t, however, repeat this troubling diagnosis that he had provided about Cruz on Monday: “This guy is sick. There’s something wrong with this guy.”

Meanwhile, lots of Americans, regardless of political ideology, are queasy about this all-too-accurate boast from Trump during Tuesday night’s victory lap:

“We won the evangelicals. We won with young. We won with old. We won with highly educated. We won with poorly educated. I love the poorly educated.”

Certainly the GOP, regularly reviled as the party of privilege, needs to reach out to the poor, who just so happen to frequently be poorly educated.

After all, not everybody can attain the lofty academic credentials of Trump, an alumnus of the University of Pennsylvania’s Wharton School of Business — or of us St. Andrews High School, Trident Technical College and Clemson graduates.

Pop quiz (being “poorly educated” doesn’t exempt you from taking it, answers at column’s end):

1) Name the prominent Clinton supporter who, in reply to a reporter’s question, said in Columbia on the day of the 2008 S.C. Democratic primary: “Jesse Jackson won in South Carolina twice, in ’84 and ’88, and he ran a good campaign. And Senator Obama is running a good campaign.”

That comment was reasonably construed as being dismissive — and in a racially insensitive way — of Obama’s lopsided victory.

2) Name the author who writes in his new book: “In my opinion, it was Donald’s fault that the (U.S. Football League) didn’t survive. Now don’t get me wrong. I like Donald. I hold on to my wallet when we shake hands, but I like him. I just think his personal ambition sank the USFL. He was interested in only two things: money and publicity.”

And: “In the years since, every time Donald runs for president, I pray he never gets the chance to do to the USA what he did to the USFL.”

Alas, one third of S.C. Republican primary voters rejected enlightening insights from some of my previous columns (and from some of this newspaper’s editorials) about the folly of voting for Trump.

That raises another frightening question:

Which of these two increasingly likely possibilities is more ominous?

1) Trump gets the nomination, then loses in November.

2) Trump gets the nomination, then wins in November.

Then again, if you didn’t vote in the S.C. GOP primary, you can vote in the Democratic one on Saturday.

That way, even if Trump gets the GOP nomination, you can still cast at least one ballot against Clinton this year by voting for Sanders.

And if Clinton gets her party’s nomination, perhaps you should vote against her twice this year — even if that helps make “The Donald” the president.

1) Bill Clinton tried to rain on Obama’s 2008 S.C. Democratic primary victory parade with that remark. Obama romped in that primary with 55.4 percent of the vote to just 26.5 percent for Mrs. Clinton and 17.6 percent for John Edwards, then went on to win the nomination and the White House. Former President Clinton later complained that the Obama team had “played the race card” on him during the primaries.

2) Burt Reynolds, with Jon Winokur, offers those cautionary revelations about Trump in “But Enough About Me, A Memoir.” Reynolds, who played halfback at Florida State before injuries ended his football career and forced him to stoop to show biz, was a co-owner of the USFL’s Tampa Bay Bandits (named for his movies “Smokey and the Bandit” and “Smokey and the Bandit II”). Canadian tennis player/businessman/movie producer John Bassett was the team’s principal owner.

The USFL played its only three seasons (1983-85) in the spring and summer. Then Trump, as owner of the New Jersey Generals, sold fellow owners on going head-to-head against the NFL by switching to a traditional autumn/winter schedule for the 1986 season. That stupid play call permanently sacked the USFL, which folded before even kicking off its planned fourth season.

But at least Steve Spurrier, the only head coach the Tampa Bay Bandits ever had, didn’t quit on that team in the middle of a season.
