Patrick Morrisey, Republican challenger to Democrat West Virginia Sen. Joe Manchin, released a fourth television campaign ad Friday in which he criticized Manchin for “pushing a gun bill supported by Obama liberals.”

President Donald Trump appears in the ad twice telling a packed West Virginia rally crowd last week, “A vote for Morrisey is a vote for me”:

“Patrick Morrisey is protecting our Second Amendment. He is endorsed by the NRA and West Virginia gun owners,” the narrator says as images of Morrisey talking and looking over firearms flash across the screen. Morrisey’s A+ NRA rating and endorsements from Gun Owners of America and West Virginia Citizens Defense League are branded over the video. “Liberal Joe Manchin is lying to West Virginia,” the narrator continues.

Morrisey’s campaign highlighted Manchin’s D rating from the NRA upon release of the ad.

Video footage of Manchin holding a firearm then flashes over the screen with audio of him saying, “And the Second Amendment always.” The ad throws a large red X over the words “protect second amendment.”

“Joe Manchin’s pushing a gun bill supported by Obama liberals,” the narrator then declares. “The NRA calls Manchin’s gun control ‘revenge against gun owners.’ Lying liberal Joe’s gotta go.”

Trump’s message at the West Virginia rally, “A vote for Morrisey is a vote for me,” flashes for the second time to close the ad.

Manchin was the sole Democrat who voted for cloture on the nomination of Judge Brett Kavanaugh for the Supreme Court on Friday morning, though it was not the deciding vote. It remained unknown at the time whether he would ultimately vote yes or no on Kavanaugh’s confirmation. This comes as Manchin slid to a narrow four percent lead over Morrisey in a Senate Leadership Fund poll that revealed five percent of voters were still undecided. A competing poll from the Democrat Global Strategy Group showed Manchin leading Morrisey by double digits.
