This says that the Tea Party is preventing the Republicans from asserting their majority control over the Democrats. So conservatives have prevented the passage of an Obamacare repeal and replacement and now holding up a spending bill to prevent a government shutdown. So a small minority of conservatives is holding up the Republican majority which is giving power to the Democrats and Pelosi. The Tea Party and conseravatives are just as obstructionist today as they were with Boehner and Obama, despite Republican control of both Houses and the Presidency.
