Here is an article by Paul Krugman (as far from a Conservative as you can get) talking about how Obama's tax plan doesn't effect just people making $250,000. It is now down to $182,000.
Here is how Krugman describes it:
"What about the claim, based on Joe the Plumber’s complaint, that ordinary working Americans would face higher taxes under Mr. Obama? Well, Mr. Obama proposes raising rates on only the top two income tax brackets — and the second-highest bracket for a head of household starts at an income, after deductions, of $182,400 a year."
