No, my ideology hasn't changed. Their current platform is wide open enough to accommodate pretty much any ideology, and I figure they deserve to have a libertarian caucus pushing them in the right direction.
Am I optimistic that they'll change the direction of American politics? No.
If they do change the direction of American politics, am I confident that they'll do so in the right direction? No.
But since my own party of more than a quarter century has fallen to a hostile takeover, I figure that the portion of my time that I devote to electoral politics is kind of up for grabs and I might as well give these guys their shot at it.
