Do not discuss Norm Coleman's record -- its verboten

Al Franken has introduced ads (here and here) that criticize Sen. Norm Coleman's poor voting record. Despite assuring Minnesotans that his record was fair game back in April, he always reserves the right to go back on what he said in the past.

GE: So you're record is fair game?

Norm: Absolutely. Absolutely..."
(MPR's Midday)

Norm is whining that Al's ads are negative, inaccurate attacks. If this race is about Norm's record, Al Franken will win this race. So Norm's campaign roles out the Norm-speak^TM to counteract the discussion of Norm's voting record:

The Coleman camp fought back Monday in a media missive that characterized Franken as "vulgar" and "dishonest," claiming that he had distorted Coleman's record and had been the first to air an attack ad.

If you read the entire article, you will notice that Norm can't point out what specifically Al got wrong. If you read the blog post at Norm's campaign site, they cannot refute any of the points Al makes.

Which part is inaccurate? Norm hasn't rubberstamped Bush's invasion and occupation of Iraq? I think Norm still claims that one. Norm hasn't played cheerleader while Bush drove the economy into the ditch? I'm sure Norm doesn't want to talk about that. Norm hasn't voted for tax cuts for the wealthiest Americans? Norm would like you to think of this as stimulating the economy. Vulgar? I didn't hear any cuss words ... maybe Republicans exist in a parrallel universe?

The sole reason Norm objects is because the claims in these ads are irrefutable.
