One of the two most thorn-in-Democrats’-side senators rather brazenly planted her flag on the filibuster today — and she did it at a … Mitch McConnell event of all places.

Calling Sen. Kyrsten Sinema (D-AZ) the “most effective first-term senator” he’s seen in his decades in the upper chamber, McConnell introduced Sinema ahead of her speech and Q&A at the McConnell Center at the University of Louisville.

“She is, today, what we have too few of in the Democratic Party: a genuine moderate and a deal-maker,” he said.
