I am absolute sick to death of political game-playing. Vote for the candidate who most closely matches your values. If everyone did this rather than trying to game the system, we would have a Congress more in tune with main street. You want the RINO, vote for the RINO. You want someone else... do that instead.
Frankly, as much as Castle votes with Obama (even Cap and Trade while admitting he didn't even read it), I'd rather have a Dem than a RINO who will give the Dems political cover of "bipartisanship".
While some claim the majority postition is worth accepting some Rinos the problem arises when we get a percentage that is a big enough show-stopper to become instead an Agenda Setting Clique.
We they get Lindsey, McCain and other media drama queens rushing to be at the head of such a coalition and we have the Gang of Eight crap all over again.
