I dislike the idea of putting civil rights up for a vote

[HereSince1628]

13. Do you mean the 2006 Referendum on marriage equality amendment? That was not a citizen initiative.

It was a requirement of the process for amending the state's constitution. It was placed on the ballot by the legislature action after the amendment was passed in two consecutive assemblies.

Regarding citizen initiated referenda in WI the following statement comes from the Wisconsin Legislative Reference Bureau, "Governing Wisconsin" pdf... http://legis.wisconsin.gov/lrb/gw/gw_13.pdf

on page 1 middle column a line or two below the 2nd and third order headings "DIRECT LEGISLATION"
and "Initiative in cities and villages"

"Unlike many states, Wisconsin does not provide for a statewide initiative process." http://legis.wisconsin.gov/lrb/gw/gw_13.pdf
