We have a family member coming to town just for this rally and has asked to bunk at our house. Love this relative to death but it's gonna be an interesting few days. 
Awwwww, you need to put a little care package for them to take to the rally, maybe give them a sign that says FU DU, and explain to them that the DU is basically DUbya's name shortened, and pack them a nice little lunch of 2 slices of bread but no cold cuts, explain that because of Obama and Democrats you need to cut back on expenses, and as Jess suggested, a roll of toilet paper and tell them there's going to be a porta potty shortage and they may have to go in the bushes.
Any other suggestions we can give to Dixie to make her relatives protest more comfy?
