The latest fight between Tea Party and establishment Republicans is a familiar one: ObamaCare.
The Tea Party is ready to take a stand on defunding the divisive healthcare law and willing to risk a government shutdown in the process.
Establishment Republicans worry the strategy will repeat the Clinton-era government shutdown showdown, which hurt Republicans in the 1996 elections.
Tensions will reach a boiling point after the August recess, when lawmakers start negotiations over how to keep the government open.
In the meantime, old-guard Republicans are sending a clear message to conservatives: The shutdown isn’t worth the risk.
On Friday, Sen. Tom Coburn (R-Okla.) said that a plan to shut down the government to block funds for ObamaCare would cost the GOP control of the House and could destroy the party. ------ Tensions between the John McCains and the Rand Pauls of the GOP have flared over the last three years as establishment Republicans vie for power with the Tea Party insurgency.
But keeping the government open could prove the biggest battle yet, since the current funding bill expires just as ObamaCare's major provisions are scheduled to take effect.
The law's new insurance exchanges open for enrollment on Oct. 1 and coverage kicks in Jan. 1, along with the individual mandate to carry healthcare coverage.
Given the timing, Rubio and his peers say the stakes couldn't be higher.
“If this issue isn't important enough for us to draw a line in the sand on, what issue is?” the Florida Republican said on the Senate floor Thursday.
