MADISON, Wis. (AP) _ State Rep. Brett Hulsey has announced his candidacy for governor.

Hulsey is the fourth Democrat to declare a bid for governor. Mary Burke, Marcia Mercedes Perkins and Hariprasad Trivedi have declared their candidacies. Burke is widely viewed as the front runner among those three, however.

Hulsey says he has a plan to reinvest more than $2 billion to create clean energy jobs, increase job training and send more money to public schools, the University of Wisconsin System and technical colleges.

Hulsey has been in the state Assembly for four years and served on the Dane County Board for 14 years. He runs an energy and environmental consulting business.

Hulsey hits the campaign trail swinging. On Mitch Henk's "Outside the Box" program Monday morning, he refers to Burke as a "spoiled rich kid", who has the personality of a potato.  Hulsey calls Governor Walker's first term a "reign of terror".

A Burke campaign spokesman said Hulsey's candidacy won't change Burke's strategy. A Walker campaign spokeswoman didn't return requests for comment.
