The effort in Wisconsin is part of a national campaign in Republican-controlled swing states to aid the party's presidential prospects. Republican National Committee Chairman Reince Priebus, a Wisconsinite, has endorsed the proposals that have emerged in Pennsylvania, Virginia, Michigan and Florida, as well as his own state.

But the movement has stumbled out of the gate, with high-profile Republicans like Virginia Gov. Bob McDonnell and Wisconsin Gov. Scott Walker balking at the changes.

“One of our advantages is, as a swing state, candidates come here. We get to hear from the candidates,” Walker told the Milwaukee Journal Sentinel. “That’s good for voters. If we change that, that would take that away, it would largely make us irrelevant.”
