James Joyner over at OTB has his thoughts.
My immediate thoughts are as follows: Why is it that everyone benefiting from the Bush/Cheney era is aligning with Mitt Romney?
And why is it that all the Reagan supply siders, the ardent pro-lifers, and the budget and military hawks are uniformily falling in line with McCain?
I hate to put it in such stark contrasts, but those are the legacies that McCain and Romney are respectively championing. Is McCain vs Romney turning into a clash between the values of Reagan vs. the values of Bush?
