The Republican Presidential Field

Republican presidential politics are in a state of confusion. The party base is conservative on economics, national security and social issues, but the most socially liberal of three leading contenders is leading in party polls: pro-choice, three-times-married, Rudi Giuliani has the edge at the moment over John McCain and Mitt Romney. Conservative Republicans have booed McCain and evangelicals are openly skeptical of Romney's Mormon religion. Will the party base give up its "litmus test" on social issues to get a hawk on national security? Are both moderates and conservatives looking for new faces? We hear from journalists, politicians and evangelicals.
