Though, "conservatives and libertarian voters" will turn out anyway

From Eric Dondero:

Initiatives and referendum for repeal of ObamaCare will be on the ballot in a number of states this Fall, including Missouri, South Carolina, Oklahoma, Arizona and Florida. The initiatives are seen as a way to help boost turn-out on the Right. But some on the Right, don't see it as entirely necessary. Conservatives and libertarians are already fired up.

From The Hill "Republicans put health reform on ballot in push to turn out conservatives":

“We don’t care who gets it done,” [repeal] said ALEC health task force director Christie Herrera, “just as long as they get it done.”

Herrera said she doesn’t think Republicans need the ballot measures to bring out the vote.

“I think you’re going to see huge turnout among conservatives and libertarian voters,” she said, “just because there’s huge residual anger against the health reform law.”
