Don't know. I personally would like to see Sen. Tammy Duckworth run.
She is a disabled WAR vet who had her Helicopter shot down by an RPG where she lost her legs,
She went on to be a Congressmen and now a Senator , she has a real good voting record on Veterans affairs , and women's and children's affairs.
I have written her and asked her to think about it she said she would but haven't head anything more on the subject.
IMO she would be a very good President, but then again who ever is the next President will have to spend most of their first term just fixing the mess Trump has made and won't get to do much of what they want to.
