With Depleted Primary Field, Romney Looks to Win Big Republicans in five states are voting Tuesday in primaries that party leaders hope will serve to accentuate Mitt Romney's status as the presumed nominee for the fall election against President Obama. Mr. Romney remains short of the 1,144 delegates needed to clinch the nomination, and even the 231 total delegates at stake Tuesday won't change that reality. But with the support of a growing chorus of party officials, Mr. Romney has moved on - as evidenced by the fact that he will deliver a victory speech Tuesday night in New Hampshire, a state whose role in the primaries is long over but which could be a key swing state in the general election. Still in the race - for now - are Newt Gingrich, the former House speaker, and Representative Ron Paul of Texas. Both men have pressed on even as they have acknowledged that they can't win enough delegates to be the nominee. Mr. Gingrich has spent the last several days focused on Delaware, where his campaign hopes he can pull off a kind of upset over Mr. Romney. Mr. Gingrich has said that he might "reassess" his campaign if he doesn't win there, leading to talk that he might pull out of the race. "This has been a good opportunity for us, we have been here seeing a lot of people," Mr. Gingrich told NBC. We have got really positive responses and I would hope we would do well here - either carry it or come very, very close. Mr. Paul has continued to campaign aggressively, holding well-attended rallies as he pushes his message of fiscal discipline and foreign restraint. He also has been organizing at state and district conventions and has increased his delegate haul in states like Iowa and Minnesota. Also on the ballot - but no longer in the race - is Rick Santorum, who dropped out two weeks ago but has yet to endorse Mr. Romney's bid to be the party's standard-bearer. Despite abandoning his bid, Mr. Santorum could receive votes from conservatives eager to send a message to Mr. Romney. News organizations are not paying for exit polling in any of the states that vote on Tuesday, leaving cable news commentators and others with little sense of how the contests might go. Mr. Romney's campaign has signaled that it intends to move quickly after Tuesday's primaries to integrate its operations with the Republican National Committee, which has up to now has tried to remain neutral in the intraparty nomination fight. And the Boston-based campaign has already begun to ramp up its fund-raising as Mr. Romney moves into the general election. That effort will accelerate even further after Tuesday's primaries, especially if the results encourage Mr. Gingrich and Mr. Paul to end their quest for the nomination.
