Oops.

This morning, about 12,500 voters in Florida's Pinellas County received a robocall from the county election supervisor's office...telling them they could drop off their absentee ballots TOMORROW.

They can't.

The call tells voters who requested mail ballots they had until 7 p.m. “tomorrow” to get them turned in. They actually must get them in by 7 p.m. tonight.

The calls were supposed to go out Monday, according to Pinellas County Supervisor of Elections spokeswoman Nancy Whitlock.

"Apparently, there were still some in the queue. They were supposed to be stopped at 8 last night, but evidently they didn't all go through," she said.

The calls went out between 8 and 8:30 a.m. before they were stopped.

Whitlock says "corrective" calls have been made.

The Pinellas County Supervisor of Elections is Republican Deborah Clark, a Republican who is up for re-election today.

A similar thing happened in Orange County, Fla., where a candidate for tax assessor blamed a vendor for robocalls today telling people to vote tomorrow.
