Just three days after debuting his stump speech in Iowa over the weekend, Wisconsin governor Scott Walker announced that he had set up a fundraising committee to support a likely presidential bid.

The group, Our American Revival, is ostensibly intended to promote “policies that restore power to the states and their people”; that’s an indirect way of saying it will serve as a vehicle for Walker to explore a run for the White House and house policy hands and fundraisers while he continues to govern his state.

Walker has in recent weeks begun to make it clear that he is serious about running for president. He hired Rick Wiley, a former political director at the Republican National Committee, who will serve as campaign manager if he gets into the race, and David Polyansky, a Republican strategist who most recently lent a hand to Joni Ernst’s successful Senate campaign.

The Wisconsin governor can boast about something many politicians can’t: He has actually accomplished something. His success in stamping out collective-bargaining rights for public-sector unions drew national attention — and a recall election — and made him a hero in the Republican party. During the recall, money poured into Wisconsin from donors around the country. And in 2016, as Jeb Bush and Mitt Romney float potential presidential bids, there remains a restlessness among the party rank-and-file for fresh faces who have nonetheless burnished their résumés with executive experience and real accomplishment.

Despite his success, Walker’s low-key nature, so impressive in contrast to the jeering protesters who once surrounded the state capitol in Madison, has prompted questions about whether he has the star power to outshine his competitors in what will be a large Republican field. There are also lingering questions about his ability to raise the millions of dollars necessary to fund a campaign. Some argue that his recall election attracted the attention of the party’s top-dollar donors, donors who were happy to give to that effort but who are likely to support a candidate like Jeb Bush in 2016.

Walker and Our American Revival will test those premises.
