Governor Ventura took his cabinet to Mankato yesterday for the official roll-out of what he calls his "Big Plan." The Plan is the Governor's comprehensive vision for the rest of his term in office, and it emphasizes his philosophy of governing, rather than offering specific new policy proposals. The few legislators who attended the speech reacted with caution, and at least one lawmaker says he has a hard time taking Ventura's policy statements seriously, in light of Ventura's Playboy interview.
