Can Republican Study Committee Changes Help Save the GOP Health Care Bill?

Can Republican Study Committee Changes Help Save the GOP Health Care Bill?: Health care legislation proposed by Republicans to replace Obamacare has received a barrage of criticism from outside conservative groups, as well as a number of prominent members of Republicans' own caucus, such as Sen. Mike Lee. Many have speculated that the current bill is dead on arrival.
However, the Republican Study Committee is proposing some changes to the way the bill reforms Medicaid that could go a long way toward fixing one of the most objectionable parts of the bill. Via Politico:
The group, which rarely takes positions on amendments in committee, supports a proposal from Reps. Joe Barton (R-Texas) and Marsha Blackburn (R-Tenn.) that would freeze Medicaid enrollment under enhanced Obamacare rates at the end of 2017, two years sooner than the GOP repeal bill allows.
The group is also backing an amendment from Rep. Morgan Griffith (R-Va.) to institute work requirements in Medicaid for able-bodied, childless adults.
