I stand with Bush on this. The Democrats didn't give a damn when the 527's were going to town on Bush, then it was freedom of speech or whatnot. But then, when it happens to them, they go crying about how unfair it is.
Bush has taken the appropriate response. He has stayed above the fray, refusing to comment on the Kerry ad, and saying he feels Kerry served honorably. Yet, he's calling for Kerry to stand with him on calling for an end to the 527's entirely, which Kerry refuses to do. Bush has taken the right stance. Kerry's stance has been opportunistic. Of course, Bush is benefitting from all this... the grand irony is that he's been calling from the beginning to end the very thing that he's now getting a boost from!
If Kerry really wants this stuff to be brought to an end, he should not play a double standard when it comes to Bush. Either end it all or don't condemn any of it.
