Barack Obama may be a new sensation, but when it comes to taxes, he sounds very familiar: Tax the rich. In fact, attack the rich.

The other day he said, "It's high time the rich pay their fair share."

The crowd roared — I guess they weren't rich.

But do they know who is? Does anybody?

When I asked a liberal friend the other day ripping the greedy fat cats who've had it so easy, I interrupted him to ask who those greedy fat cats were.

He immediately said, "All those CEOs."

When I asked which CEOs, he simply added, "All of 'em."

Yet CEOs are hardly poster children for the rich or indicative of the rich. Maybe the very, very, very rich. But not the very, very... or even the very... or certainly just not even the rich.

Most people who ponder this think the rich are millionaires. Millionaires are rich. But Barack Obama defines the rich — those who've had a free ride — as any one making more than about $200,000 — $250,000 for couples.

That's a lot. But is that rich?

In places like New York and Chicago and L.A., I imagine you'd get some argument.

But no matter, they're bad. Time to tax 'em good.

But doesn't that also assume they're not taxed pretty good as it is? They pay a top rate of 35 percent. Obama wants them to pay closer to the 40 percent it was when Bill Clinton was president.

It's only fair. It's only right. But is it fair or right to assume the hundreds of billions liberals want to spend on programs can be paid for taxing just the rich?

No. You have to go further down. The math simply doesn't support not going further down.

But you won't hear people roaring for that.

So they don't hear that. Even though, I suspect, deep inside, they know that.
