WASHINGTON — For more than three decades, the Republican Party brand has been deeply tied to a worldview in which the aggressive use of American power abroad is both a policy imperative and a political advantage.
Now, a new generation of Republicans like Senator Rand Paul of Kentucky is turning inward, questioning the approach that reached its fullest expression after the terrorist attacks of Sept. 11, 2001, and signaling a willingness to pare back the military budgets that made it all possible.
Put this together with Senator Rob Portman's crystallization of the Republican inner angst over marriage equality, and you begin to see the remaking of the GOP (for the third time in about 20 years).
