@roger,
Hey, if that's your opinion, that's your opinion and I won't try to argue you out of it.
But it certainly saves time and energy when folks are honest about their motivations. If someone says "I like Romney because
x," and I know that
x is not true, I might say something.
If they say "I'm voting Romney because he's not Obama" then we'll both be happier if I don't waste my breath.
