So?
Does that mean he shouldn’t have performed his job for the last year or so?
He belongs on that list just like the others.
For practicality's sake, the situation is not the same for a House member. If Hunter resigned at this point, there would have to be a special election scheduled held, but since House members are elected every two years, the "special" election would be put off until the general election in November. If a Senator's term were to expire at the end of the year as is Hunter's, I would allow them the same consideration. However, in Liebermann's case, his term did end, yet he ran for re-election to the Senate at the same time he was running for VP. To me, this is just plain wrong.
In Hunter's case (as with any House member), I will concede that he probably knew he was going to run for President as he ran for re-election in 2006, so he should have resigned his seat then. This also would apply to Sen. Clinton who should have refrained from seeking re-election to the Senate in 2006 since she knew she would be running for the Whitehouse in 2008.
