(Madison, WI)  —  Madison Mayor Paul Soglin is asking his supporters to spread the word that he will run for governor. Soglin says he will make his campaign announcement in a few weeks, but first he wants to see the potential benefits of using Facebook. He says social media will play an important role as he runs after thinking about the idea for the last seven months.  Republican Governor Scott Walker has called the 72-year-old Democrat an “unabashed throwback to the 1960s radical liberal.” Soglin has been Madison’s mayor for several different terms since 1973.
