George Conway turned to profanity and a Janis Joplin lyric on Saturday as he sought to explain why President Donald Trump refuses to spend money on his fellow Republicans ahead of the midterm elections — a decision host Eugene Daniels described as "strange."

Conway, a prominent Trump critic, conservative attorney and co-founder of the anti-Trump Lincoln Project, appeared on MS NOW to lay out his theory about why Republicans keep pleading with the president to tap into some of his $400 million super PAC funds for their cash-strapped campaigns. His remarks come as party committees and outside groups have long depended on the president's fundraising power to finance down-ballot races, making any hesitation by Trump himself a point of friction within the party.

"The problem is he does not give a s--- about anyone other than himself," Conway said. "Trump is the most narcissistic human being we have ever seen in American politics. Full stop."

Conway rooted his argument for Trump's "malignant narcissism" in the origins of the president's political career, claiming the same personality trait explains both his rise and his eventual downfall. He has advanced this analysis before, frequently citing the psychological framework of "malignant narcissism" in his public commentary on the president.

He urged viewers to remember the country before Trump took office, arguing that Americans at the time were worn out by being told they had to help the poor and needy. That is when he invoked Joplin.

"It was kind of like the Janis Joplin song, 'Lord, won't you buy me a Mercedes Benz,'" Conway said. "It's about the gospel of getting rich — and so that was the appeal of Trump... He gave a permission structure for everyone to be their worst selves."

While Americans imagined a society of people who cared only about themselves, together, Conway argued, Trump had other plans.

Those plans are now on full display, Conway claimed, as Trump sits on his campaign war chest and dodges assassination threats alongside his human "binkie."

"He is the malignant narcissist, the sociopath," Conway said. "These people become more and more delusional over time because they create their own little world. That's what Natalie Harp is about. She protects him."

Harp, a former One America News host, has served as a Trump aide known for delivering supportive news coverage and praise to the president.

The constant praise from Harp, Conway concluded, explains why Trump has failed to grasp that his actions could trigger a "midterm reckoning" in the upcoming elections. Midterm cycles historically pose a stiff test for the party holding the White House, which has typically lost ground in Congress — a dynamic that heightens the stakes of Trump's spending decision for vulnerable Republican incumbents.

"His aides won't tell him... negative things," he said. "They'll just say, 'Boss, your message hasn't really gotten out — it's our fault.'"
