He has a stronger organization than any other Republican
Paul starts with a built-in base of libertarians that comprises at least 10 percent of the GOP electorate, and his boosters have made tremendous inroads in state parties around the country.
They may be a minority, but they are a devoted one. Paul supporters will drive farther and work harder than any other 2016 contender’s core backers. They also tend to be younger and engaged on social media and the blogosphere in ways that people who support someone of the older generation like, say, Jeb Bush are not.
His challenge is to cultivate those loyal to his father while at the same time broadening his appeal beyond libertarians. Inside the so-called liberty movement, there’s some frustration with the younger Paul for endorsing Mitt Romney last year during the Texas Republican convention — which critics believe cost the elder Paul delegates. Some also worry about nepotism in a movement that prizes merit.
But the drone filibuster shored up most of the Paul loyalists, who had gone a bit wobbly lately.
