The problem with that is the same thing we make fun of with leftists. No matter how many smart "Rightists" out there do that and more stuff he wouldn't come up with, people like him will still find a stupid person to point to and say they are right.
That said, I don't necessarily think doing that will suddenly win the Jewish vote. The big tent strategy only works for so long before all those extra people say no to everything you try to do because they disagree with your fundamental views. Pleasing everyone gets you 2000 page bills being voted on and $30 Trillion in debt.
