I think the appeal of Trump this election cycle is due to the loss of faith in the republican/democrat establishment , leadership or whatever you want to call it.
Rove and Clinton represent the worst in American politics. Since the dems appear to not only be leaning to the far left, but are falling off the ledge, I will have to give my support to Trump.
I have no idea if he can do the job, but I feel confident he will try and do the right thing. If he succeeds, other politicians will fall in line and there will be a chance for real change.
If he's just fooling us all, it will be no worse than having another career politician leading us down a path self destruction.
