Dems do a lot for returning vets.
they charge us with atrocities and accuse us of acting like Gengis Kahn (Murtha, Kerry, Gore, Pelosi, Shroeder, etc.)
they try to charge us for our combat related injuries (Obama)
they vote for a war and send us to one, then promptly sabatoge the war effort with charges (see above) and cut off funding
(Vietnam, Desert Storm, OIF, OEF)
they manufacture political talking points about what they lie about having been briefed (Pelosi is prime but they all did)
they are briefed on classified plans and leak the invasion warnings to the opposition (Grenada)
here is a very fundamental point - if one sends the forces there (including voting in the Congress for the war effort or authorization for the use of military force) and then campaign against the war, one is betraying the sacrifice and service of the troops who went.
oh yea, lots of real support there.........
