Former Republican U.S. Sen. Dave Durenberger on today's turbulent politics

There's been no shortage of talk about how turbulent and divided politics are in our country right now, with the aisle between Republicans and Democrats seeming to grow wider all the time. 

Former Republican U.S. Senator Dave Durenberger remembers another time in politics, one in which he says elected officials worked together more frequently to turn good ideas into policy. He represented Minnesota in the Senate from 1978 to 1995. 

His new book, "When Republicans Were Progressive," written with the Star Tribune's Lori Sturdevant, tells the story of the progressive Republican Party he says worked for Minnesota — and the ideals it could lend to politics today. 

The book comes out this Saturday, September 15, and there'll be a book launch party at the Minnesota History Center on October 16. You can find more details at mnhs.org.
