I am an independent with no party affiliation but from an ideological viewpoint, I am well to the right of center. Still, I cannot support Mitt Romney for president. While Barack Obama has not performed to expectations for a variety of reasons (some of which are his own failings), the dilemma in this election is that the alternative to Obama is Romney.
Having worked directly with Romney during his term as Massachusetts governor, I can tell you that there is nothing authentic or genuine about him. He'll tell you what he thinks that you want to hear and pretend to be what he thinks you want him to be.
He's an ideological chameleon who will say anything to get your support and then do whatever he wants to favor the rich and privileged; he's a caricature of the stereotyped Republican Party.
