To help some on the right refute those on the left when they make this fallacy as an argument please remember...
Something right does not become wrong if...
You are a Republican...
You were in power...
You lost an election...
You didn't act on it on strongly enough before...
You didn't complain loudly enough about it according to some...
You did it yourself...
All these are attacks on CREDIBILITY or attacks on the person. Correct principles are still correct regardless of the person presenting the argument. Deficit spending the next generation into oblivion is still wrong no matter who can be blamed for what percentage when and is still wrong to continue regardless of who is in power.
