What did work? Who did win?

Tammy Duckworth won Barack Obama's old seat in the Senate, defeating Mark Kirk, a moderate republican who had distanced himself from Trump. There are many reasons she won, some were things that she didn't control like Illinois being as blue as a summer sky. But she ran with endorsements from Unions and big names, her compelling story, bit of an independent streak and a ton of cash. Her opponent did himself no favors when he tried to make a joke about Duckworth's heritage. Kirk was too middle of the road for the conservative base and there were few Democrats in Illinois willing to cross the ticket for him.
