North Carolina's Republican Senate primary field has expanded to seven candidates with the entrance of Dr. Edward Kryn (R). 

Kryn doesn't seem to have much, if any, chance at winning the nomination — he has no name recognition and is new to American politics, though he says on his website he ran for office in Canada before moving to the U.S. 17 years ago.

But even minor candidates could increase the likelihood that no GOP candidate reaches 40 percent in the primary to face Sen.

State House Speaker Thom Tillis (R) is the preferred candidate of establishment Republicans, but Baptist minister Mark Harris (R) and Dr. Greg Brannon (R), a Tea Party favorite, both have gained some traction in the race.

"I left medicine in Canada as I saw my own profession embark on a secular path that turned its back on the Hippocratic Oath as it came to embrace abortion and the homosexual agenda," Kryn says in his campaign bio. "I felt my only recourse would be a move to this country where 17 years ago the winds of modernism had not yet fully found fertile soil."

Kryn says experience gives him a leg up on fixing the medical system.

"As the only GOP candidate in the 2014 primary who has worked in socialized medicine, I feel that I bring a unique ability to address the deficiencies of health care without saddling ourselves with Obamacare."

Hagan is a top GOP target, and recent polls have found her running about even with the field of little-known Republican candidates.
