“I think the Ryan budget is a strong positive step that doesn’t go nearly far enough,” said Sen. Ted Cruz (R-Texas), a leading conservative voice in the upper chamber.

“I’d like to see it completely repealed,” said Sen. Marco Rubio (R-Fla.) when asked about the treatment of the healthcare law in the House GOP budget. Rubio’s position is consistent with the one adopted by presidential nominee Mitt Romney last year, which trumped Ryan’s on the GOP ticket.
