House Republican leadership is furious with ultraconservative Sens. Mike Lee (R-UT) and Ted Cruz (R-TX) whom they see as hobbling their efforts to secure an achievable spending victory by insisting on threatening a government shutdown over the unachievable goal of defunding Obamacare. House GOP leaders want to pass a continuing resolution that jams Senate Democrats with lower spending levels while forcing a vote -- without the risk of a shutdown -- on Obamacare.
