He said Tuesday that term limits will motivate lawmakers to work more quickly and ensure an infusion of fresh ideas.  

The proposal wouldn't apply to Gov. Scott Walker or anyone in the Legislature at that time it's passed. Instead, it would start in 2020 and limit newly elected Senate and Assembly members to no more than 12 years in office, and restrict the governor and lieutenant governor to eight years.

Gannon is proposing a constitutional amendment, which means that both houses of the legislature must pass it before it goes to the voters.
