The Office of Management and Budget issued a memo urging government agencies to prepare for partial government shutdown.

Both sides are blaming the other, naturally.

If the government doesn’t shut down over ObamaCare, who will get the blame? Seriously. With conservative activists demanding a goal-line stand on “defunding” the president’s 2010 health law, House and Senate Republicans are in a back-and-forth over who should be responsible for running out the clock. Not surprisingly, each side thinks the other should be holding the football when time expires on Sept. 30.

[“Whether we win or lose will be decided in the House…” — Sen. Ted Cruz, R-Texas, on “Hannity”]

Back to you, Boehner – One of the leading proponents of the defunding strategy, Sen. Ted Cruz, R-Texas, made it clear on Wednesday that he and his band of fellow conservatives won’t be able to block Senate Majority Leader Harry Reid from stripping out a “defunding” provision the House is expected to pass in a government funding bill in the coming days. Cruz has been trying to stir grassroots support for the “defund” movement, which some in the House apparently took to mean that he would lead a filibuster and engage in all possible tactics to hamper Reid’s efforts. Cruz issued a statement, though, saying Reid has the votes to proceed and called on the House to hold the line.

Rep Sean Duffy his Facebook page:

Today, Senator Ted Cruz & United States Senator Mike Lee called on House Republicans to “stand firm, hold their ground, and continue to listen to the American people” on defunding#Obamacare.

House Republicans have stood firm. We have voted to defund, repeal & delay #Obamacare dozens of times. It is time for Sens. Cruz & Lee to show they can hold the line against Senate Democrats.

Let’s hope they do not surrender before the fight even begins.

Can Americans count on Sens. Cruz & Lee to join us?

Rep. Tom Price:

Here’s the statement that Cruz, Mike Lee and Marco Rubio released:

“Today’s announcement that the House will vote to defund Obamacare is terrific news,” said Sen. Cruz. “Just a few weeks ago, this was deemed impossible. We commend House leadership and House Republicans for listening to the people and for taking decisive action to stop Obamacare, the biggest job-killer in America.

Harry Reid will no doubt try to strip the defund language from the continuing resolution, and right now he likely has the votes to do so. At that point, House Republicans must stand firm, hold their ground, and continue to listen to the American people.

President Obama has already granted Obamacare exemptions to big corporations and Members of Congress; he should not threaten to shut down the government just to deny those same exemptions to hard-working American families.”
