Well let's see Toomey(the guy you support, I also) says he agrees more with Arlen Specter, yet you wish to see the election of a person who disagrees more with the guy you support(Toomey).It depends on how the question is asked. If you ask me who I think is a better choice for the Senate between Hoeffel and Specter, no brainer on the latter. But if you ask me who I think is a better choice for the Judiciary Committee chair, Specter or Hatch (or Sessions or Kyl or Grassley) it is also a no brainer in the other direction; I think if Toomey was being truthful he'd also say that he thinks compared to the others Specter is not the right man for the judiciary chair. He won't be asked that, and he won't say it on his own though.
And to me, the Judiciary chair is more important than a single Senate seat. It may not be to you. We all have our own judgments to make.
I am glad to see you say you support Toomey. If me deciding to go against his wishes is objectionable to you, then how did you ever support him in the first place since it went against the wishes of someone else you support (Bush, as do I)?
It's called a primary and that is what primaries are for. Toomey has stated that he will support Specter in the next and biggest battle, the general election.
