ANNAPOLIS, Md. — Former House Speaker Newt Gingrich says his campaign will have to stay on a tight budget to make it to the convention.
Gingrich says he has enough to keep going, but his campaign must stay on "a fairly tight budget" to reach the Republican convention in Tampa, Fla.
Gingrich was campaigning Tuesday in Annapolis. He is criticizing Gov. Martin O'Malley's proposal to raise taxes on gasoline.
Gingrich says he will be talking about his plan for energy independence at an event later in Salisbury.
Maryland's primary, with 37 delegates at stake is set for next Tuesday. Rep. Ron Paul is scheduled to be at the University of Maryland, College Park, on Wednesday. Mitt Romney was in Arbutus last week.
