I believe that the difference here would be that Rand is not seen as weak on Israel like his dad is....
Remember that Rand did visit the office of Kristol and his core allies.
To fool Kristol and his ilks, Rand said that he's more moderate on Israel issue than his father.
So it's not surprising that Palin endorsed Rand.
However, Rand has turned out to be the great defender of the Constitution like his father.
Rand did outsmart Kristol, Palin and their ilks (Bravo!) with his victory.
However, make no mistake.
Every 'Israel firsters' in this country knows that Ron Paul cannot be bought and paid under any circumstances.
Ron Paul would NEVER, EVER allow to sacrifice American lives on behalf of Military Industrial Complex or Israel.
The recent Ron Paul ad is 100% accurate when it said 'No Deal'.
That is the different between Ron and Rand.
Rand was unknown so he could pull that off to Kristol and Palin and their ilks.
Ron is very well known in his position and principle already.
