Kavanaugh booster flames out spectacularly on MSNBC after calling accusations about judge’s temperament ‘racist and sexist’

Republican confidence in Judge Brett Kavanaugh appeared diminished on Saturday as Republican commentator Carrie Sheffield launched an long-winded rant trying to defend the nomination during an appearance on MSNBC's AM Joy.

Host Joy Reid refused to go to commercial break in order to allow the extraordinary segment to continue.

"What happened in the hearing was a fundamental miscarriage of justice," Sheffield argued. "There is zero evidence of this sort of behavior."

After Sheffield claimed that, "every single supposed eyewitness has refutably denied it," Reid interrupted conservative activist.

"Hold on, that's not true," Reid noted. "I want to make sure we don't get that into the public consciousness, that is not true."

Moments later, Sheffield claimed that in 2008, Democrats made out Sen. John McCain (R-AZ), "to be the great Satan."

"Hold on, hold on, hold on," Reid interrupted again. "Wait, wait, wait, wait, wait."

"So that didn't happen, I just don't want you to get out anything that isn't true," Reid noted. "Once you say it on TV, people will believe it. I don't want you to say things that aren't true."

"Carrie is very wrong about all of it," noted MoveOn spokesperson Karine Jean-Pierre.

The MSNBC anchor then had to correct Sheffield on the nomination process for Judge Merrick Garland, who was never even given a hearing by Senate Republicans.

And Reid later had to interrupt Sheffield as for criticizing the victims who have come forward with sexual assault allegations against Judge Kavanaugh.

"We're not going to compare and say one person's response is superior to others," Reid said, laying down the rules for her show. "Everybody's response is different, everybody reacts differently."

"We're not going to shame Christine Blasey Ford for the way she handled it," Reid demanded.

"No one who performed the way he did on Thursday deserves to be even a judge," argued former Watergate prosecutor Jill Wine-Banks. "That showed a lack of judicial temperament -- I wouldn't want my case to be heard by him."

Sheffield replied that the comments by Wine-Banks were both racist and sexist.

"Carrie, this is incredibly weak," CNBC's John Harwood stated.

Yet Sheffield continued.

"Carrie, Carrie, Carrie, Carrie, Carrie, hold on," Reid interrupted again. "I just need to let John Harwood respond."

"Carrie is just throwing up a lot of stuff. Jill didn't say white men don't deserve justice, that's preposterous," Harwood concluded.

"Carrie, you are just railing ineffectually," Harwood concluded. "You are just railing, this is not reason that you're offering."

Yet Sheffield continued lashing out.
