I thought similarly but was always suspect because I too, am black. People suggested I just wanted to see a black man in the White House (which wasn't my motivation).
I was just attracted to his insistence on principle. I have to be honest though, and confess that sometimes Keyes strikes me as bitter and full of himself. I still love what he says, for the most part.
Capt, Dr. Keyes is a brilliant man full of himself for sure. So is Buckley. So is a host of others full of themselves at their intellectual level. But truth be told, Dr. Keyes, unlike many of those others so full of themselves, make perfect common sense. And no, I don't agree with all of his stated principle, but I shared enough with him that we were on reasonable enough common ground that I cast my vote for him in the primaries. The man makes sense. He speaks truths like no politician I have ever heard in all my 50 plus years. So much so that when the republican party rejected him, and they did, no mistake about that, this 20 year veteran Republican found the Libertarians. I found my party. I am home. We don't color and we don't divide. We just do freedom. And me, well I am all about freedom. So it is perfect for me.
Keyes has recently revealed his agenda and it's so much like that of the fanatic radicals of the 1850's and '60s republican party that I can't support him at all anymore. He has become a raving bystander and is dooming himself to the sidelines.
