Rob Simmons is attacking Joe Courtney on taxes.
Which prompted this response from Courtney:
Taxes are an old saw. Nancy Johnson attacked Chris Murphy for voting to raise taxes as a state senator. Simmons is basically taking the same line against Courtney.
Except that unlike Murphy, who is currently a state senator, Courtney hasn't been in the legislature for twelve years. Then again, voters don't know that, and they probably don't care.
Simmons has attacked his rivals over their stance on taxes before. He attacked Jim Sullivan for voting to raise taxes while a member of the Norwich city council during the 2004 campaign, for example, and attacked Sam Gejdenson for some of his tax votes, as well. It works. People respond. It's also the sort of attack that is very, very hard to defend against. In most cases, all a politician can do is work to change the subject.
That's what Courtney is doing in his ad: changing the subject to Rob Simmons and George Bush. We'll see which issue voters care about more.
