Don Blankenship at center of party-backed super PAC primary fight in West Virginia

The controversial Don Blankenship is running for Senate in West Virginia.

Democrats have rolled out six-figure ads attacking two GOP primary candidates Evan Jenkins and Patrick Morrisey through the Duty and Country super PAC.

The group, led by Robert "Booth" Goodwin, a former Democratic gubernatorial candidate, has spent nearly $1.4 million attacking the two West Virginia Republicans in the past two weeks.

Goodwin was also the very U.S. attorney that prosecuted Blankenship during the federal trial.

She then snatched the final victory away from him in the general election.

Other high profile Republicans have weighed in as well with their take on the race.

Duty and Country spokesperson Mike Plante denied claims that the group’s goal is to steer the GOP primary in favor of Blankenship.

“The Republicans are taking care of attacking Blankenship,” Plante said.

Duty and Country’s strategy to target Jenkins and Morrisey, he said, is merely based on their data that indicates that either candidate is going to win the Republican nomination.

Walsh, however, said the Democrats' motives are clear.

Nominating Blankenship would ensure Manchin’s re-election, and that the Republican leadership is rightfully concerned about his candidacy.

“Otherwise, you don’t generally waste money in a primary,” added Walsh. “You want to preserve that money for the fall when you have all the attention.”

Senate Majority PAC spokesperson Chris Hayden declined to comment on whether his group is involved in the operations of the Duty and Country PAC but said that his organization is focused on supporting Manchin in the general election right now.

Senate Majority PAC has spent about $2.2 million in support of Manchin so far this election cycle.

West Virginia University political science professor Patrick Hickey said regardless of whether the Democrats are attacking Jenkins and Morrisey with the intention of benefiting Blankenship, it will have the effects of doing so.

“I think it’s a smart strategy from the Democratic side to increase the effectiveness of the other candidates’ attacks,” Hickey said.

Republican campaign consultant Ford O’Connell said the GOP has learned lessons from the 2012 Missouri Senate race -- they will not sit by idly and watch Democrats meddle in a GOP primary.

Mountain Families PAC’s $681,000 ad debut highlighted Blankenship’s involvement in the coal mine tragedy calling him a “toxic coal slurry.”

Hickey said the multi-million dollar attacks against Blankenship linked to the establishment could backfire on the national Republican effort.

“West Virginia has been a state with a relatively low socio-economic outcome, low health outcome, low educational outcome for decades,” Hickey said. “West Virginias are tired of the status quo and want to try something different, and I think that’s part of his (Blankenship’s) appeal.”

Blankenship has been vocal about his distaste for the GOP leadership in Washington, calling the national Republicans a “liberal establishment” during a recent debate on FOX News.

He also just launched a full-on war against the GOP establishment, calling the Senate majority leader “cocaine Mitch” in a new ad. He later released a statement saying the name referred to allegations a shipping company run by Elaine Chao's father transported drugs.

McConnell and Chao are married.

The senior Kentucky senator told Fox News he doesn't "have any comment about ridiculous observations like that."

Earlier this election cycle, it was thought the rivalry between Jenkins and Steve Bannon-backed Morrisey would result in an aggressive GOP primary.

O’Connell said Republicans don’t seem too concerned either way as of now, as long as Blankenship doesn’t seize the nomination.

“And they (the Democrats) know that’s the whole key to shutting this site down,” O’Connell said.

Meanwhile, some of the top Republican donors have been backing Morrisey.

A super PAC called the 35th Inc., backed by big name Republican donors including Richard Uihlein, Bernard Marcus and the Koch Industries, has spent $844,266 supporting Morrisey and attacking Jenkins.

The single biggest political contributor this year, Uihlein is also behind two other super PACs bankrolling ads in support of Morrisey -- Americas PAC and Restoration PAC.
