Milwaukee Mayor Tom Barrett has sent a letter to the chairman of the Democratic National Convention asking that Wisconsin’s largest city be considered for the party’s 2020 event.  Barrett promoted features in the downtown area like the brand new state-of-the-art arena as the main venue.  He says Milwaukee has plenty of hotel rooms and transportation alternatives for the thousands attending the event.  The letter was sent to D-N-C chairman Tom Perez.  The Democratic National Committee is expected to narrow its list of candidate cities sometime in late summer.
