WHERE ARE THEY NOW? Alvin Greene, celebrity candidate, lives in obscurity, approves of Donald Trump.

In 2010, the unemployed no-hoper famously walked in from his home in the cornfields of Clarendon County, plunked down $10,440 of his Army G.I. pay to run for the U.S. Senate with absolutely no political experience.

Now 41, Greene became an overnight celebrity as a result — The Washington Post and outlets nationally and internationally carried stories — after recording a surprisingly easy 30,000-vote primary win over Democratic establishment favorite Vic Rawl, a retired Charleston County judge.

It made Greene the nominee to take on powerful GOP incumbent Jim DeMint.

It didn’t matter he had little grasp of the issues, had no staff, no cellphone or computer and would be criminally charged with showing obscene material to a coed at a University of South Carolina computer lab.

To be fair, some of that was probably the Dem establishment seeking revenge. But now:

For a Democrat, he’s also willing to speak heresy: He supports President Donald Trump.

“I think he’s doing better than President (Barack) Obama and the Democrats were doing eight years ago,” he said.

Maybe he should run again.
