Sen. Ron Johnson starts the 2016 election cycle as the most vulnerable senator on the map. He’s undefined in the eyes of many, polling shows; and he’s running in a state that has gone Democratic in seven straight presidential elections. To boot, there are rumors that Democrat Russ Feingold, who Johnson unseated in 2010, may run. Feingold would start with high name recognition and a loyal liberal following.
Personally, I hope former U.S. Senator Russ Feingold decides to run against Sen. Johnson in 2016, because Feingold certainly would bring the kind of name recognition and ability to raise money that it would take to reclaim the seat he formerly held.
