1) She's been in the federal government for 8 years, four years of which as VP - more experience than most first-time Presidents.

And that might be a selling point for you...if a former President wasn't running against her.
The facts of the matter is that Trump had a run of 4 relatively peaceful years where he crushed ISIS and there were no major conflicts around the world.

Can Harris say the same thing?

2) She seems to have learned a great deal while serving as Veep - her recent performance in moving from running mate to managing the pressure-cooker of an unprecedented shift at the top of the ticket shows a very high level of competence.

You keep hammering this point, but a) polling wise she's...exactly where Biden was before the debate and b) your gratitude should go to Dave Plouffe and the Obama team, who are now running her campaign.

3) I would have thought last night would have disabused you of that.

No it did not. She refused to answer any questions, took no positions, and just repeated talking points. What does "opportunity economy" mean? Where were details of her proposals?

She offered none and the moderators didn't push her.

She's a good debater.

She was never "fact checked" in real time, got no tough questions and refused to answer what she did get.
