Liberal Flip-Flopper

It strikes me as odd that no one is making a counter-argument to the political charges leveled against Senator Kerry.  And it makes me wonder why the smart strategists really aren't in politics.

Specifically, the Bush campaign calls Kerry a liberal.  It also attacks him a flip-flopper who is on every side of every issue.  Aren't those two claims contradictory?  You are either a liberal who is out of step with the mainstream values of this country, or you are a opportunistic politician who takes both the liberal and the conservative side of every issue.

The Republicans need to decide which argument to use - the liberal values one, or the unsafe tilter-in-the-winds.  Otherwise, they'll give the Kerry camp a chance to bring out their centrist credentials and undermine both charges.
