I've noticed, as has Jim Robinson, from my reading of his posts, that one of the first tactics of the Giuliani supporters was to attack Reagan, or Bush, or whoever, in a bid to make the liberalism of their candidate look less egregious. Sorry to see Romney's supporters forced to adopt the same foolish tactics.
Heck, start your own party
No need, as yet. We've already got a party, with a pro-life, pro-family, pro-America platform. It's called the GOP.
I'll try a boilerplate EV response: 'What does pointing out the extreme liberalism of Republican presidents have to do with anything? It's not a tactic, its the truth if you can handle it.'
