Progressive-Democratic Party Presidential candidates and Senators Elizabeth Warren (D, MA) and Bernie Sanders (I, VT) disagree with each other on whether Sanders ever told Warren that a woman could not win an election for President. That disagreement came to the fore in Tuesday’s Progressive-Democrat primary debate, and became manifest in a post debate, still on the debate stage, spat between the two:

“I think you called me a liar on national TV,” Ms Warren said, according to audio released by CNN.
“What?” Mr Sanders responded.
“I think you called me a liar on national TV,” she repeated.
“You know, let’s not do it right now. If you want to have that discussion, we’ll have that discussion,” Mr Sanders said.
Ms. Warren responded: “Anytime.”
“You called me a liar,” Mr Sanders said.

Do you think this spat will influence voters as Democrats move forward to the primaries?

It certainly should influence voters in the general election. What the exchange demonstrates is that it isn’t possible to disagree with a member of the Progressive-Democratic Party. The one who disagrees must be a liar or must be calling the one with whom he disagrees a liar.

In Progressive-Democrats’ ideology, disagreements can’t possibly be differences of interpretation, and they certainly can’t ever be matters of saying that one or the other is mistaken.

No. The one is must be a liar or must be calling the other a liar. That’s a deliberate, consciously done effort to suppress dissent, to stifle disagreement. It’s an attack on free speech.

And it’s what we can expect, nationally, should a Progressive-Democrat occupy the White House.
