Here's William Weld speaking to a Libertarian Party audience not long ago:
Q: I want to make sure that you are going to stick through to this to the end, no matter what threats you get from the Republican Party. And by the way, will you run even if you don't get the Republican Party nomination?
A: Yes and yes.
What the Libs didn't realize: Yes and yes is street slang for no way, suckers.
