One thing is very common about Common Ground… they can be bought.

Leaders of Common Ground — the community group most critical of public funding for a new Milwaukee Bucks arena — said Friday they will change their position on arena funding after news that they prevailed in a separate campaign involving a company chaired by Bucks co-owner Wes Edens.

Nationstar Mortgage, a Dallas company chaired by Edens, will contribute $30 million to address residential foreclosure problems in the city.

Common Ground has held protests in recent months with a list of demands for Edens-chaired Nationstar Mortgage to provide addresses of foreclosed and vacant houses to the city of Milwaukee, invest money in a fire-damaged house on the city’s west side and donate other properties to nonprofits.

Common Ground also has made demands for more than a year that if the public is going to help pay for a new downtown arena, then $150 million of public funds should go to repairing or replacing playgrounds and school athletic facilities in Milwaukee County. The campaign is called Fair Play.

Common Ground is just another shakedown organization looking to line their own pockets.
