(FOX NEWS) — Mitt Romney pulled off a three-primary sweep Tuesday night, bolstering his bid to pivot from Republican front-runner to presumptive nominee.

The former Massachusetts governor won the contests in Wisconsin, Maryland and the District of Columbia, Fox News projects. He further solidifies his front-runner status, while leaving Rick Santorum an increasingly distant second.

During his victory speech in Milwaukee, Wis., Romney mapped out what appeared to be his general election message. He vowed to rebuild an “opportunity society,” while panning President Obama’s vision as one of a “government-centered society.”
