Disgruntled former employee, associates with traitors, proven liar.
What they can say? This is for starters.
Powell can be accused of associating with Richard Clarke, the former counter-terrorism director under Bush who wrote a detailed, precise book which as an inside participant described Bush and Cheney's approach to the war on Iraq and dereliction of duty in other areas.
He also associated with Scott McLlelan, for former press person for Bush who wrote a damning tell-all book.
Powell took the information supplied by Cheney and lied to the UN.
Unsavory character. One wouldn't want his endorsement.
Powell may be too big, the endorsement coming too late or it may not be worth in an apparently lost cause for them to do this, but they would.
