Can Democrats actually stop the nomination of Brett Kavanaugh?

It doesn’t “imply” that at all. It implies they want to get Justice Kavanaugh confirmed before the SCOTUS term starts in OCtober.

What “rushing” are you talking about? Previously I posted this:

Kavanaugh was nominated on July 9th. That was 69 days ago, and it’s still probably another 10 or so until his final confirmation vote. That’s not “rushed”. Its right in line with the nominations of previous SCOTUS justices.
