What is Tommy's Definition of "Positive"?

About a week ago Tommy Thompson went on Fox News and he was directly asked if he was going to go negative with his ads.  Thompson responded saying, "no...no we're positive."  Is Tommy not in charge of his own campaign, was he simply being dishonest or doesn't he know the definition of the word positive?

Since making that promise on Fox News he has released nothing but nasty negative ads.  The first one out of the gate started by telling the 2010 Lie of the Year.  The next one was little more than the substance free name calling of his opponent. Now, only a week after promising to run "positive" ads he is continuing to go down the same dark road as the sleazy D.C. special interest groups that support him. The Milwaukee Journal Sentinel is reporting on a new Thompson ad that combines the worst elements of those that came before.  It repeats the 2010 Lie of the Year and it devolves into more mindless name calling.  They also throw in the words "San Francisco liberal" for its dog whistle effect I'm sure.

Yet Tommy Thompson just promised one week ago that his ad campaign would be "positive"? It sounds like he doesn't know the meaning of that word any better than he knows the meaning of the words "do away with".
