Former Republican Florida Gov. Jeb Bush chastised the heavy-handed approach his party has used in its fight to stop Obamacare, saying "self-restraint" would be a more effective tactic.

"Tactically, it was a mistake to focus on something that couldn't be achieved," Bush said in an interview with ABC's "This Week," referring to the GOP's approach to link stopping Obamacare with legislation to fund the government and raise the federal debt limit.

Bush said that because the health care law is "flawed to its core," Republicans would be wise to simply let it fail on its own.

"So have a little bit of self-restraint. It might actually be a politically better approach to see the massive dysfunction," he said. "But we don't even hear about that, because we've stepped on that message.

"Republicans need to just take a step back and allow — show a little self-restraint and let this happen a little more organically."

He added that the best way for Republicans to repeal Obamcare is to devise an alternative health care plan.

"We never hear the [GOP] alternative," he said. "We could do this at a much lower cost with improved quality, based on our principles, free market principles."
