Political strategist Joe Trippi has seen the future of presidential politics, and he says it's libertarian. When it comes to issues that are important to young voters-domestic spying by the N.S.A. and the legalization of marijuana, for example-libertarians are in touch with issues that the establishment won't go near, says Trippi. Public outrage has forced mainstream Republicans and Democrats to address the constitutionality of drone strikes and the expansion of presidential powers. But, he says, the political establishment will almost certainly do nothing more than tinker with a status quo that it helped to create. Libertarian issues don't have enough support from within either party to win a presidential nomination, argues Trippi, but the Internet makes much of the partisan machinery irrelevant. He believes that crowdfunding is replacing $5,000-a-plate dinners, and door-to-door campaigning is obsolete in the era of Facebook and "big data" analytics.
