Yeah, it would be wrong to criticize a presidential candidate during a campaign, unless your accusations are fabricated, like Dan Rather's about Bush. Then it's OK.
These unions bash Wal-Mart non-stop and then curl into the fetal posotion when Wal-Mart responds. This is exactly what the Left did in 2004 when they bashed Bush over his Guard service, "Bush lied", etc. but when the Swift Boat Vets responded..."Now, now there's too much discourse and negativity in politics blah blah blah..." They remind me of Ric Flair who used to "beg" for mercy when he was getting beat down only to sucker-punch the opponent when he wasn't looking.
