Can troops stationed abroad vote?
 

Given that they're in the thick of things, I'm curious if troops stationed overseas can still participate in the election?

I'm pretty sure they vote absentee.

The short answer: Yes.

The long answer: Yes, but their vote may not get counted. Absentee ballot requirements vary from state to state (for instance, some require a witness to sign a form), and given the number of absentee ballots a lot of states are having to send overseas to troops, this complicates things. Some states were not prepared and have not necessarily allowed for the needed turnaround time that sending a ballot over there and back again requires.

Have you had your head buried in the sand for the last few weeks? There have been a few stories out there in the news about troops voting, namely saying that there were a number of difficulties in 2004 and only about 30% of the troop vote was counted, and that they expect similar difficulties this time around.

Here is an article from CNN that explains what's going on: Ballots from U.S. troops risk being discarded - CNN.com

Yeah. What she^ said.

Yes, they can vote, but it can sometimes be a complicated and convoluted process. The problem is with the service member's home state (state of record) not the military. The Armed Forces make every possible contigency to ensure that servicemen can vote.
