Gingrich Announces Campaign End Date

UPDATE: Newt Gingrich will bring his presidential campaign to an end on Wednesday, a full week after the former House speaker announced his plans to drop out of the GOP race.

According to Gingrich's website, he'll officially suspend his presidential campaign at 3 p.m. at a press conference at a Washington, D.C.-area hotel. His staff had previously suggested that he's "more than likely" to formally endorse Mitt Romney once he's out of the race.

Slate's Dave Weigel has a look at what Gingrich has been up to during the final days of his campaign here.

Wednesday, April 25: Looks like it didn't take Newt Gingrich long to "reassess" things.

Fresh off Tuesday's 0-for-5 primary performance, the former House speaker has decided to end his presidential campaign, sources close to the campaign tells both Fox News and CNN.

The exact details are still being worked out, but Gingrich appears likely to make it official with a speech in Washington, D.C. next Tuesday. Sources tell Fox that he is "more than likely" to formally endorse Mitt Romney.

Tuesday, April 24: The race for the GOP nomination appears all but sewn up for Mitt Romney, but voters in New York, Connecticut, Delaware, Rhode Island, and Pennsylvania will nonetheless have their chance to cast their votes on Tuesday. 

While the results of the nominating contests matter relatively little now that Rick Santorum has dropped out of the race, the final tally in Delaware has the potential to deliver another dash of good news for Romney: a Newt Gingrich exit.

The former House speaker told NBC News that he'll have to "reassess" his campaign depending on how he fares in the the First State, which will hand out 17 delegates in its winner-take-all nominating contest. "We have got really positive responses and I would hope we would do well there—either carry it or come very, very close," Gingrich said.

Romney, meanwhile, will be spending the day in New Hampshire, a potential swing state come November. CNN explains that he appears a lock to win the lion's share of the 204 delegates up for grabs in the five states voting on Tuesday.

The Associated Press notes that the GOP front-runner is expected to move toward the center as he faces off with Obama, as he did Monday when he endorsed Obama's call to freeze the interest rate on subsidized college loans at its current lower rate. Obama is campaigning in swing states on the issue this week, presumably to rally the youth vote.
