Obviously none of them would've voted for Bush.
How many of the 19 do you think will vote for Kerry/Edwards?
Don't be so sure... "Suspected terrorist" Sami Al-Arian actively campaigned for President Bush in Florida in 2000 and attended a White House meeting in 2001, yet the Republican Party is criticizing former USF President Betty Castor for not firing him after the FBI began investigating him in 1995.
Apparently, terrorists support Bush.
Moreover, at that time Sam al-Arian (Florida), the North American leader of the terrorist organization Palestinian Islamic Jihad (PIJ) - responsible even for the death of Americans - was active in the Bush 2000 campaign and visited the White House.
Things have changed though. The Arab & Muslim communities are not going with Bush this time mostly due to the WoT.

As far as I can tell, most dead people vote Dimocratic and I would assume that dead terrorists would most certainly vote for SKerry. I've had a hard time finding reliable polling data.
