Washington caucuses (40 delegates): Santorum hoping for a victory. Three delegates go to the winner of each of the state’s 10 congressional districts, an invitation for strong competition.
March 6 (Super Tuesday, seven primaries, three caucuses, 419 delegates total)
Alaska caucuses (24): Delegates are awarded in proportion to the statewide vote. Paul may fly there in search of an elusive victory.
Georgia primary (76): Gingrich’s home state when he was in Congress, and anything other than a victory would resurrect talk of a campaign exit.
Massachusetts primary (38): Romney could win all of the delegates in his home state.
North Dakota caucuses (28): Santorum made three stops in the sparsely settled state in a single day recently, and hopes to add it to his list of earlier caucus victories in Iowa, Minnesota and Colorado. Paul is also hoping for success.
Ohio primary (63): A big battleground state, although the results of the Michigan primary on Feb. 28 are likely to reset the race instantly. As elsewhere, Restore Our Future, the pro-Romney Super-Pac, got the jump in television advertising.
Tennessee primary (55): One of the states Gingrich hopes will launch a comeback, and polling currently shows a competitive three-way race in a state that allocates delegates in proportion to the popular vote.
