WASHINGTON (AP) -- Mitt Romney scored a hard-won, home state triumph in Michigan and powered to victory in Arizona Tuesday night, gaining a two-state primary sweep over Rick Santorum and precious momentum in the most turbulent Republican presidential race in a generation.
Two other candidates, Newt Gingrich and Ron Paul, made little effort in either state, pointing instead to next week's 10-state collection of Super Tuesday primaries and caucuses.
Romney's Arizona triumph came in a race that was scarcely contested, and he pocketed all of the 29 Republican National Convention delegates at stake in the winner-take-all state.
Michigan was as different as could be -- a hard-fought and expensive battle in Romney's home state that he could ill afford to lose and Santorum made every effort to win.
Returns from 71 percent of Michigan's precincts showed Romney at 41 percent and Santorum at 37 percent. Paul was winning 12 percent of the vote to 7 percent for Gingrich.
