“We’re not going to have a result tonight,” Oz, the cardiac surgeon, author and well-known celebrity physician, told supporters at his primary night event in Bucks County, in Philadelphia’s northern suburbs.

Oz, who until the launch of his Senate campaign late last year was host of TV’s popular “Dr. Oz Show,” predicted that “after the votes are tallied, I am confident that we will win. We are making a ferocious charge.”

With the two candidates virtually tied as Tuesday turned into Wednesday, McCormick told supporters at his gathering in Pittsburgh that “we’re not going to have resolution tonight, but we can see the path ahead. We can see victory.”

McCormick, a former hedge fund executive, West Point graduate, Gulf War combat veteran and Treasury Department official in former President George W. Bush’s administration, vowed that “we’re going to win this campaign.”

But with the margin currently within the 0.5% that triggers an automatic recount, it may be awhile before a winner is determined.
