Understand something. The left never asks any Democrat the hard questions, nor do they study any Democrat’s voting (or personal) history too closely, because none that matters in their world.
To them, the leftist agenda is everything. Character defects and wrongdoing on the part of a left wing politician are of little, or even no concern to them.
This is why the media, Del voters, and the Uniparty let him skate. He represented all the ideals and policies they agree with. They knew what he was when they elected him, but they didn’t give a damn.
It's the media, like ABC, CBS, CNN, NBC, MSNBC, The New York Slimes, Washington Compost, etc that never asks hard questions of the rats. All the ask are softball questions.
