What's Up in Idaho and North Dakota?

These are the only two states not represented on a list of contributors to the campaigns of Scott Brown and Martha Coakley in the last three weeks of their campaign.  For details, see here.  Many find it surprising that residents in the other 48 states gave to one or the other of the candidates (Brown: 48 states;  Coakley: 44 states).  But with the 41st vote in the balance, it should be no surprise the election generated such national interest.  My question is what the heck is going on in Idaho and North Dakota?  Are they pathetically out-of-touch or far more evolved than the rest of us?  I am starting to lean toward the latter explanation.
