Originally positioned by the Republicans as a smart female political newcomer and seen as a credible challenger to Senator Jeff Merkley (D-OR), Monica Wehby has become a damaged candidate with diminishing changes of success.

“I’m not a politician,” she said in announcing her candidacy in January 2014. So, far, that’s pretty clear. A pediatric neurosurgeon at Randall Children’s Hospital, she has been tripped up almost from day one.

It’s not as though Merkley should be a particularly strong opponent. Winning the first time by just 49% to 46%, he’s a pretty colorless Senator with one of the most liberal voting records and without any significant legislative accomplishments.

With today being the first day of the federal fiscal year, Merkley can also be fairly targeted as a Senator who has done nothing to effectively deal with the burgeoning national debt, now at $17.5 billion and counting, that is going to burden all our children.

Merkley is also running at a time when the country overall is in a pretty sour mood, with 67 percent of registered voters saying the nation is on the wrong track (NBC/Wall Street Journal) and 57 percent of registered voters nationwide saying it’s time to give a new person a chance in Congress (NBC/Wall Street Journal).

But if the polls are right, that doesn’t seem to matter to enough Oregonians to make Merkley vulnerable.

Instead, Wehby has been left defending herself against such things as charges arising out of opposition research that she harassed a boyfriend and her ex-husband. As Joe Pounder, a veteran GOP researcher, told Politico, “There’s the growing intensity of a media cycle fueled by the salacious and voyeuristic.”

Likely opposition research that generated reports on the website Buzzfeed in September that multiple portions of position documents on Wehby’s website had been plagiarized also has slowed any Wehby momentum.

Despite Wehby’s efforts to position herself as a new choice, and the significant support she’s been getting from independent spending, it’s pretty clear at this point that she hasn’t broken out to capture the hearts, minds and votes of enough Oregonians to win.
