KEY POINTS
  • Sens. Rand Paul, Dean Heller and Shelley Moore Capito say they will vote for the procedural motion in Republicans' push to repeal the Affordable Care Act.
  • Republicans can only lose two votes and still approve the procedural motion.

Three crucial Republican senators said Tuesday they will vote for a procedural motion in Republicans' push to repeal Obamacare, a boost to the GOP effort in what is expected to be a tight vote.

The support from Sens. Rand Paul, Dean Heller and Shelley Moore Capito makes passing the motion to proceed later Tuesday a much more realistic goal. All three opposed previous versions of a repeal or replacement plan.
