Only the great masters of style ever succeeded in being obscure, wrote Oscar Wilde. He wasn't talking about Paul Ryan's tax plan but I'm certain he would have paid him that compliment.

Asked how he would pay for the plan he and Mitt Romney are proposing - a 20 percent across-the-board income tax cut - on Fox News Sunday, Ryan said it would take him 'too long to go through all the math.'

So let's skip that, eh? Math is hard.

I've watched some entertaining shell games in my time but I've never seen someone take $5 trillion in tax cuts for millionaires and billionaires, then decline to tell us how they'd be paid for without raising taxes on the middle class or exploding the deficit.

Perhaps he won't tell us his plan for the middle class because, strange to relate, he doesn't have one?

It seems a simple enough request. Isn't he referred to as the GOP's numbers guy? A brief summation would suffice. If he can't or won't explain himself to us then why should we vote for him?
