Henry Enten at FiveThirtyEight has a good round-up on how the GOP has been shifting away from Rand Paul on national security:
And so Republican attitudes have flipped since 2013. According to Pew’s latest data, 57 percent of Republicans believe that U.S. anti-terrorism policies don’t go far enough in protecting the nation, and just 30 percent think we are going too far in restricting civil liberties. The percentage of Republicans who think we do too little to solve the world’s problems is up 28 percentage points, to 46 percent. The share who think we do too much is down to 37 percent.
