But Bolton didn’t enter the race. Why? Republican voters (and the majority of candidates) returned in 2014 to their hawkish roots. This shift coincided with the rise of the terrorist group Islamic State, which took control of a quarter of Iraq and a third of Syria last year and released widely circulated videos of beheadings, with victims including U.S. citizens. Republican lawmakers criticized President Obama for, among other things, referring to Islamic State as the “JV team” and not responding more forcefully to the threat.

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.

Paul may have forced the expiration of parts of the Patriot Act late Sunday night, including the National Security Agency’s ability to collect telephone metadata, but his views haven’t spread to other Republican candidates. All three of the leading contenders have come out against Paul in his fight, even though House and Senate Republicans are a little more split.
