For a variety of reasons, Rell hates RINOs Rob Simmons and Sam Caligiuri (who while RINO is probably the least RINO-ish of all the candidates). I'm not sure what she thinks of RINO Tom Foley or Paulite Peter Schiff. Anyway, Rell and McMahon are best buddies.
So this is for real in your opinion - not just a stunt?
Also, McCain-Feingold means her ability to self-finance gives her a huge advantage, especially in the primary.
