From the WSJ today:
Politico: John McCain hung his final presidential debate performance on an Ohio plumber who campaign aides never vetted. A day after making Joseph Wurzelbacher famous, referencing him in the debate almost two dozen times as someone who would pay higher taxes under Barack Obama, Mr. McCain learned the fine print on the plumber’s not-so-tidy personal story: He owes back taxes. He is not a licensed plumber. And it turns out that Mr. Wurzelbacher makes less than $250,000 a year, which means he would receive a tax cut if Mr. Obama were elected president
Oh, how very embarrassing. Every good speaker knows to check their source of information before using it in a speech. You would think that a presidential candidate who is behind in the polls would have been a bit more cautious on the content used in the debate. I guess your never too old to learn.
