GOP Senate rival slams Blankenship over mine explosion

West Virginia Republican Attorney General Patrick Morrisey took aim Monday at Don Blankenship, his rival for the Republican Senate nomination, for the explosion at a Blankenship-run coal mine that killed 29 miners.

The new Morrisey ad comes as Republicans scramble to keep Blankenship, a controversial former coal executive and ex-convict, from winning Tuesday's primary. GOP observers fear that a Blankenship primary win would sink the party's chances of defeating Sen. Joe ManchinJoseph (Joe) ManchinDemocratic Senate emerges as possible hurdle for progressives  Susan Collins and the American legacy Democrats seem unlikely to move against Feinstein MORE (D-W.Va.) in November.

Morrisey's new digital ad represents the most direct attack on Blankenship's relationship to the 2010 explosion at Upper Big Branch Mine. But it's unclear if the last-minute strike can stop Blankenship amid concerns of a late surge.
"Twenty-nine miners killed at Upper Big Branch Mine, owned and operated by Don Blankenship's company. Families devastated, children left fatherless, wives widowed," the narrator says in Morrisey's new ad, with Blankenship's face looming over 29 silhouettes meant to represent the miners who died in the blast.
"Blankenship was convicted and sentenced to prison for willfully conspiring to violate mine safety standards."
The ad goes on to note that Blankenship's probation officer lives in Nevada, not West Virginia, and claims that "liberal Democrats will easily defeat" Blankenship. 
The spot is a part of Morrisey's last-minute strategy to frame the race as a choice between "a convicted criminal or a proven conservative," as the ad states at the close.
