Usually these domains are not sold frequently. I have seen many of them just staying undeveloped.
That's because after the coming elections the specific domain is not going to have any value at all (probably after 4 years it can be used again for a last time).
Tip: However you could try to sell it to some parties that are strongly against Bush and they would do anything in order not to see Bush president again. (=would do anything means they could even pay you the $150 you ask for) :D :D :D
