WASHINGTON, July 18 (Xinhua) -- Three Republican senators said on Tuesday that they would oppose a procedural vote to move forward a new GOP plan only aiming to repeal Obamacare, leaving Republicans again short of votes.

Lisa Murkowski, Shelley Moore Capito and Susan Collins indicated that they would not vote to move forward a GOP repeal of the Affordable Care Act, known as the Obamacare, to the Senate floor without implementing an immediate replacement.
