Bachmann's thought process is more analytical and thus she connects the dots in making her points very well.
I second everything you posted. I would add that she can think on her feet very, very well and seems to be prepared for the “gotcha” question. Plus, she held her composure against that moldy old gargoyle Arlen Specter, who was incredibly rude to her. She didn’t let him get to her, which was his intent.
Add me as a vote for Bachmann.
