"Mr. President, we've done the math per Rahm's request, and we've concluded that only about 20-30% of your supporters - tops - would be financially annihilated and obliterated by our plan to force everybody to purchase private health insurance. That leaves 70-80% of your voters in comfortable enough circumstances to still possibly vote for your reelection. Sir, this is doable."
