With Donald Trump's presidential victory, the future of the conservative movement has become entwined with an unconventional New York businessman better known for his deal-making than any ideological principles. Some conservatives worry whether they can trust their new president to follow decades of orthodoxy on issues like international affairs, small government, abortion and opposition to expanded legal protections for LGBT Americans — and what it means for their movement if he doesn't. "Donald Trump may have come to the Republican Party in an unconventional and circuitous route, but the fact is that we now need him to succeed lest the larger conservative project fails," said evangelical leader Ralph Reed, who mobilized his organization to campaign for Trump during the campaign. Trump has a somewhat tortured history with the Conservative Political Action Conference, an annual convention that's part ideological pep talk, part political boot camp for activists. Matt Schlapp, chairman of the American Conservative Union, which hosts CPAC, said Trump's aggressive style is more important than ideological purity. The tensions between Trump's brand of populist politics and conservative ideology will be on full display at the three-day conference, which features panels like: Conservatives: Along with Trump come his supporters, including the populists, party newcomers and nationalists that have long existed on the fringes of conservativism and have gotten new voice during the early days of his administration.
