Big,
Not to be drowned out but to persuade and lead those who happen in there but would be conservative. Look at their online petition a lot of the folks coming there are ticked off about non-secure borders, congress playing games with WOT, etc, basically center-right folks who shouldn't be left to the vultures.
We have to win in the battledground of ideas!
I'm sorry. But third parties do nothing more than draw votes away from a viable candidate.
Without 'Perot', G.H.W.Bush probably would have been re-elected.
Even with his 'no new taxes' slip up!
