Has anyone checked to see if Democratic National Committee Chairman Tom Perez is still breathing?

Let’s face it: Post-Iowa, his party is in free fall. It’s not clear any of their presidential candidates have mapped out a realistic way to the nomination, let alone to beating President Trump in the general election.

On top of that, a 5’7” multibillionaire businessman named Michael Bloomberg is sucking up a shocking level of support despite having entered the race in the 11th hour.

As if that dumpster fire needed kerosene, the Iowa caucuses were a tragic embarrassment of a mess, leaving each of the campaigns and the nation at large confounded at the lack of organization and competence by the party.

Late on Wednesday, we still didn’t know who won the most delegates coming out of Iowa.

Pete Buttigieg, the former mayor of Whoville, claimed a premature victory but apparently did do very well, despite polling nationally at around 6 percent.

But leaders in the party have a lot of reasons to be nervous about the media momentum Buttigieg is riding following the caucuses: His support among black Democratic voters remains firm at less than 2 percent, a number that looks good on milk and really bad in a general election for a party that relies heavily on that bloc for victory.

Otherwise, it looks like the Bernie Sanders surge is real, and Joe Biden’s dip is, too.

Sanders in recent weeks saw support for his campaign climb, putting him at the top of the polls in Iowa and New Hampshire. He’s in a distant second behind Biden for the South Carolina primary, but nationally, he’s within a five-point striking distance.

That’s saying a lot for the socialist, but how do you explain the appeal of the oligarch to party voters?

Bloomberg jumped into the primary just two months ago, setting the airwaves awash with TV ads. He hasn’t appeared in a single debate. He didn’t bother competing in Iowa or New Hampshire. And yet, he’s currently polling nationally in fourth place, ahead of those who had, including Sen. Amy Klobuchar and Andrew Yang.

If Bloomberg continues to rise and Biden continues to fall, I hope the DNC is prepared for a face-off between the mega-rich, pro-business cap­italist and the sort-of-rich, pro-welfare state socialist.

That should be a lot of fun.

The rest of the field is slowly and surely drifting away.

Klobuchar took to the mics amid the Iowa disarray to repeatedly declare she had punched above her weight, which may count for something — just not delegates.

Yang continues to hang in, and though he gets a lot of TV time, there has been no moment or purpose to his campaign that defines it as a capable election winner.

People no longer talk about Warren, who as recently as October seemed to match her support to Biden’s, only to then watch it steadily wilt 14 points in the wrong direction. If the Real Clear Politics average is an indicator, she’ll likely do as well in the New Hampshire primary as she apparently did in Iowa, which is to say, not well enough to boast top-tier status.

Tulsi Gabbard? No.

Tom Steyer? No.

Duval Patrick? Wait — he’s running?

Again, has anyone checked on Tom Perez?

Not to kick them while they’re still trying to figure out Iowa, but the Democrats’ biggest problem, the president, has had the exact opposite fortune in recent weeks.

During the impeachment proceedings, he made progress on trade relations with China and locked in a new deal between the United States, Mexico and Canada. His approval rating actually inched up while he waited for his acquittal in the Senate.

Then he put on a dazzling display in his address at the State of the Union, driving House Speaker Nancy Pelosi to snap, in a way the public has never seen before.

The Democratic Party, from impeachment to Iowa, is in a downward spiral.
