The Republican party doesn’t need to waste its time. Just send some dedicated and intelligent volunteers out on this, and continue on with the campaign with no further attention to it, unless those folks return with a fish.
They don’t really need that fish, though. There are plenty of torpedoes out there to sink the SS Obama.
In the most SERIOUS business of electing the leader of the Free World, and the POTUS, there are MILLIONS of people involved. To find the one fish that does Obama in requires hordes of people following as many threads as can be found to properly vet a candidate by his opposition. IF Obama is unqualified, whether it be a substance issue (foreign policy, abortion, taxes) or other issue (COLB, associations, etc), it may very well be the combined injuries to Obama that helps put McCain on top. I always bear in mind the notion of [political] "death from a thousand cuts".
