Far as I know I like Hickenlooper, even besides his wonderful name. Not remembering any negs but positive reactions from time to time. Haven't heard of Heinrich. Also have to look up Sherwood Brown, thanks for the name, Engineer.
I've got little tweaks against Cory Booker, a New Yorker article I think it was, but I forget the issue, maybe re schools. Have some neg memories re Gavin Newsom as covered in San Francisco newspapers over some stretch of time in the early oughts. Nothing to make me heavily against Booker or Newsom if I remember.
Am not up to date on Franken, might be refreshing. O'Malley, hard to get enthused.
There's a name at the tip of my tongue, a young hispanic guy from somewhere in the southwest, mentioned articles as a possibility for a Hillary v.p. choice.
Someone mentioned George Pataki as a Republican vp possibility and I've been intending to read up on him. I was interested in Kasich somewhat until I read more but that is sort of a given re an opposite party member. Similar with Rand Paul, some interest and then despair..
I didn't pair any of these with a potential presidential nominee; I'm having enough trouble juggling what I think of all that is going on with those.
