Someone please ask John McCain if he supports this

Yes, please do. Ask Senator John Sidney War Hero and Bush Fellater if he supports refusing to allow wounded Iraq veterans to register to vote if they are in VA hospitals:

On the same day the Pentagon's commander in Iraq told the Senate that new troop withdrawals could not considered for months, Secretary of Veterans Affairs James B. Peake told two Democratic senators that his department will not help injured veterans at VA facilities to register to vote before the 2008 election.

"VA remains opposed to becoming a voter registration agency pursuant to the National Voter Registration Act, as this designation would divert substantial resources from our primary mission," Peake said in an April 8 letter to Sens. Dianne Feinstein, D-Calif., and John Kerry, D-Mass. He was referring to a 1993 federal law that allows government agencies to host voter registration efforts.

My guess is that Senator John Sidney War Hero and Bush Fellater fully supports Peake on this, given that those serving in Iraq are not exactly thrilled with the prospect of yet another president attempting to resolve his issues with his father using the blood of American kids.
