The question is who is easier to beat and who is more dangerous. We aren't helping X win the election, we are setting ourselves up for a win. One of the two gets the nomination, no matter what. So who do we want and how can we influence that?
Tough call since I don't want any of the three!
I don't know who is worse between McCAin and Hillery, but I do know, Obama is worse than the other two put together, and I think he would be impossible to beat.
His supporters will not listen and will not care what his record is, or what he stands for. We will be accused of being racists and bigots and accused of hate speech. We won't be able to say a word against him!
