Maybe, but do you deny the statements, "Stuck on Stupid" and "It's Bush's Fault", are rooted in Truth?
I see nothing wrong with the repetition. Everytime they are used it re-inforces a certain point better than a paragraph ever could. It gets through to even the casual observer. Those that do not follow politics, now even joke about how the Dems put everything on Bush's head. That hurts the Dems in elections.
So does re-inforceing the idea that they are "stuck" on certain points to the height of stupidity.
No. Do you deny the fact that it is annoying and a waste of bandwidth? It's fun when it's dropped in the context of a complete thought, but wading thru endless posts of "(Fill in the blank) is stuck on stupid" starts seeming a little childish.
But that's just my opinion.
