It has been more than six and a half years since Wisconsin voters last saw a constitutional amendment question on a ballot.

That might not seem like such a long time, but here's the context: It's the longest stretch since the early days of statehood.

The only longer span was the first one, when the issues were setting term two-year terms for members of the assembly and four-year terms for senators, and raising the governor's annual salary from $1,250 to $2,500. (All were soundly rejected.)

It was eight years between the first amendment questions on the November 1854 ballot and another in 1862.

On Tuesday, the issue that goes before voters is whether to create a transportation fund that would not be able to be used for other state budgetary purposes.

Before that, the last time a proposed constitutional amendment made it to the ballot was April 2008, when voters approved limits to the governor's partial veto power.
