Sam Sloan is the Gravel type, IIRC. That is, the left wing of the pragmatic Libertarians. Right?
Not at all. And I quote from his website:
"The reason is Hillary is being pushed to the left by extreme left-wing opponents. I hope to push her back towards the middle. Also, she is not being supported by her own party leadership. One rarely or never hears any other leading Democrat speak in favor of Hillary, except for her own husband Bill. This is strange. It seems that they want her to fail."
Marc Allan Feldman is a bit of a strange type, in that his most important issue seems to be his wanting to take money out of politics. He could fit the bill.
