GOP Leaders Fret Over Potential Party Split

Even Democrats worry that the two-party system may be done

Inside the cozy enclaves of GOP bonhomie—hunkered at the tables of see-and-be-seen Washington restaurants—Republican leaders are sourly predicting a party-busting independent presidential bid by a tea-party challenger, like Sen. Rand Paul, R-Ky., in 2016.

To them, the GOP apocalypse looms larger than most realize. Dueling State of the Union rebuttals and Karl Rove's assault on right-wing candidates are mere symptoms of an existential crisis that is giving the sturdiest Republicans heartburn.

And yet, the heart of the matter extends beyond the GOP. My conversations this week with two Republican officials, along with a Democratic strategist's timely memo, reflect a growing school of thought in Washington that social change and a disillusioned electorate threaten the entire two-party system.
