Mr Kerry was and still is a liar!
They never address the statement or question they just go into damage control mode and start tossing red herrings through the air.
SIX STEPS OF LIBERAL OBFUSCATION:
1 -Twist the facts ("Swift Boat Veterans for President Bush")
2 - Make not too subtle hints that the other person isn't mentally competent ("that's just the OxyContin talking")
3 - Ridicule the opposition ("officials tried to take away his Viagra")
4 - Accuse them of sinister motives ("determination to divide Americans")
5 - Call the other person names ("portly peddler of hate").
6 - Accuse them of lying ("can't spell 'Rush Limbaugh' without the letters L-I-A-R")
But they never directly respond to the original statement.
Welcome home, and thank you for your service.
