Is the 2020 election when the Republicans lose all their remaining power in Hamilton County? 

It was a big topic of discussion on The Enquirer's That's So Cincinnati podcast election preview episode. 

University of Cincinnati political science professor David Niven breaks down the ticket in Hamilton County from Biden-Trump to Republican Joe Deters' chances of holding the prosecutor's seat to former Cincinnati Councilman Charlie Winburn's race for county treasurer.

The once-dominate Hamilton County GOP has been losing seats for more than a decade. The prosecutor's office is the most powerful local government seat in Southwest Ohio, and Republicans have gone all in on trying to get Deters re-elected. If the GOP loses the seat, it loses control of an office that's been a decadeslong farm system for judicial candidates. 

"I think the scope of Biden's likely win in Hamilton County puts the Republican Party in grave jeopardy," said Niven, a one-time aide to former Democratic Ohio Gov. Ted Strickland. "We could very easily be looking at a clean sweep for Democrats in Hamilton County regardless of the Deters name and history."

Niven's interview begins at the 6:40 mark in the episode.
