"Delaware does matter and we're looking very forward to seeing the
results tonight," Gingrich said on Sean Hannity's radio show. But the
former Speaker said "there are a lot of folks that are reassessing the
messaging process" after every election night.
Still, Gingrich seemed less definitive about his previous pledge to continue as a candidate until the convention in Tampa.
"We're going to be in Tampa whether its as an active candidate or as a leader in the party," Gingrich said. "I've said all along, the morning [Romney] gets to 1,144 delegates then he's the nominee, but he's not there yet."
Hammond told Yahoo there were three conceivable scenarios for election results, with even the worst - "doomsday" - not necessarily resulting in a Gingrich exit from the race.
"We do poorly in Delaware, Gingrich will keep his campaign schedule in North Carolina but reassess with supporters whether or not there is a path forward," Hammond says.
The campaign has events scheduled in the Tar Heel state throughout the week.
Hammond added that a close finish or victory in Delaware could expose serious flaws in a Romney candidacy.
"A win in Delaware builds financial and grassroots momentum going into North Carolina -- combined with the ABC news report that Winning our Future has $5 million to spend on TV in North Carolina could be the beginning of a chain of wins through DE, NC, KY, WV," Hammond said. "Then into a battle royal in Texas and California."
