This may work and you may find a buyer. You could develop the domains yourself though - to build up traffic and increase the value of the names.
My next comments should probably go in the miscellaneous section - but i'll say it anyway.
Even if a person has traditionally voted republican in each election, I still don't see how that person could vote for Bush again in the next election.
Our economy is the worst that it has been since the Great Depression and the Bush Administration doesn't seem to know how to pull us out of this recession.
What happened to the surplus of money that the federal government had in the mid to late 90's and the booming business?
Personally, I don't really care who is in office (repub. or democrat) - just so our economy is doing well. Bush seems to be more concerned with war than getting the economy back on track and I don't see how we are going to pull out of this recession with Bush still in office. Economically, I think it's a big mistake to vote for Bush again - it's like dooming our economy to another 4 years of recession.
Despite my comments above, I'm sure that there are some die hard republicans out there who would probably love to use your domains to campaign for the next election. Market the domains and see what happens.
