Of course Ron. Stranger things have happened and I would never presume that he will or will not run again; he will call his own shots. His fan base continues to grow, and with age comes wisdom so Ron's age doesn't bother me in the slightest.
Rand is in the circle and would also have Ron's and our tremendous support. I like much of what he does. The other things, well, voters wouldn't be so opposed.
Napolitano, absolutely, has an awesome appeal and following.
And there is Amash. #1 in my book, after scouring his voting record, and speaches. As I have eluded before, he is Constitutionally sound, and would literally rake in the younger generation, as they are now our present, and our future :-)
