Aside from the logical follow-up -- By whom? -- I'd ask those 'yes' folks the following:
- What's the argument for challenging a guy with 78% approval within his own party? And what's the game plan? It should be compelling as hell to convince millions of people that the opinions they hold are, in fact, ignorant.
- What's the endgame? By which I mean, what sort of legislation do you expect to pass if you win? And how do you plan to pass it?
- What's the plan in the event of a loss?
