Washington (CNN) As Republican leaders barrel toward a vote to repeal and replace the Affordable Care Act on the House floor Thursday, the Republican leadership strategy to court undecided members remains the same: Remind them that their bill is just one of three steps to overhaul the country's health care system.

There's one problem. Some of the most skeptical members aren't buying the so-called three-bucket strategy.

"I have called bucket three the sucker's bucket," Texas Republican Sen. Ted Cruz, who is trying to push the bill in a more conservative direction, said on CBS's "Face the Nation."

"History shows us that if you're hoping for legislative answers in the future that more often than not they don't happen," House Freedom Caucus Chairman Mark Meadows told CNN Monday. "When it comes to a repeal of a landmark piece of legislation that was ushered in by a president of the opposing party, the chances of getting eight votes for any repeal aspect would be extremely remote."

Bucket one is passing the the American Health Care Act, which would repeal the individual mandate, taxes and other key components of Obamacare. Bucket two: directing Health and Human Services Secretary Tom Price to use his discretion at the Department of Health and Human Services to make administrative change. Bucket three: pass other standalone bills to make additional market reforms.
