He’s not that hard up for votes!

The Web address Harlem politician Robert Jackson used to run for Manhattan borough president has been taken over by a German company promising to fix readers’ sexual-performance problems.

The site jackson2013.com pledges to “show you exactly what you need to do to in bed to [last] longer” and “persevere with nasty and unusual tricks.”

Jackson campaign spokesman ­Richard Fife said he did not know how it happened.

“Just like if a drug dealer moved into your former apartment, you can’t control what happens to old Web addresses,” he said.
