Polls close in Maryland and DC at 8 ET; Wisconsin’s polls close an hour later. Here’s your Google Map. In Wisconsin and Maryland, some delegates are awarded by Congressional District, but on a winner-take-all basis, with another, at-large batch in each state awarded on a statewide winner-take-all basis. DC looks to be a simple winner-take-all contest. The party leaders look to be bound to the winner in WI and MD, but not in DC. That small detail is a springboard for the statistical analysis from The New Yorker, which suggests Mitt Romney will end the campaign on June 26th with 1,122 delegates — 22 short of the magic 1,144 necessary to lock up the GOP nomination. However, as Joshua T. Putnam, a political scientist at Davidson College in North Carolina (and the author of the Frontloading HQ blog), who helped with the analysis notes, there will be about 598 unbound delegates remaining at this point. Odds that rick and Newt could lock up all but 21 of them? Probably long odds indeed.
Update: Romney wins all three, although Santorum may get the delegates for four CDs in Wisconsin.
