On many issues, getting past the culture war means an erosion of deep ideological differences. This is what McCain's Teddy Roosevelt conservatism means for the right and Obama's post-boomer liberalism means for the left. Of course they agree where others once didn't:
On immigration, faith-based social services, expanded government wiretapping, global warming and more, Obama and McCain have arrived at similar stances -- even as they have spent weeks trying to amplify the differences between them on other issues, such as healthcare and taxes. Even on Iraq, a signature issue for both candidates, McCain and Obama have edged toward each other.
The remarkable thing about this election year is that in many ways, a big shift away from the polarization of the past has already happened.
