Unless you don't care about being elected, and just want your real beliefs to influence the conversation.

Will Bernie Sanders always say what he really thinks? I'd love it if he did!

And succeed at avoiding his own marginalization?

Couldn't tell the truth if his life depended on it.

...means you think your voters were born yesterday...it's a 'do over'. For your past lies, you don't have to apologize, show remorse, regret, or the least bit ashamed, as long as you're confident. So we learned from GWB. This is one up from Tricky Dick, who at least showed regret about being caught lying (not that he lied).

Now Rand Paul is going the next step. He's not hiding his lies behind being born again, but he still expects his voters to be born yesterday.
