The victor of the Maryland primary on Tuesday will walk away from the winner-take-all contest with 37 delegates.
The latest polls show Mitt Romney running ahead of rival contenders in Maryland. The former Massachusetts governor is expected to come out on top in primaries in Wisconsin and Washington, D.C., which are taking place the same day.
HuffPost's Mark Blumenthal reports:
In Maryland, another PPP poll conducted over the weekend shows Romney heading for a blowout win with a 25-point lead over [Rick] Santorum (52 to 27 percent). A Rasmussen Reports poll conducted late last week also shows Romney far ahead in Maryland, although by a smaller, 17-point margin (45 to 28 percent). Both polls put [Newt] Gingrich in third place (with 10 and 12 percent respectively), followed by [Ron] Paul (9 and 7 percent).
