Politico names the which cities seem to be front runners for the 2020 conventions:

Democrats: Minneapolis, St. Louis, Phoenix, Milwaukee, New York and Columbus.

Republicans: Phoenix, New York, Miami and San Antonio.

Not a bad list. Arizona is an obvious battleground, and you know the Democrats will focus heavily on Wisconsin this cycle. We’ll have more on Milwaukee’s bid over the weekend.

But there is one problem with the list: Columbus isn’t bidding.
