Rep. Neugebauer (TX) on Defunding Obamacare

Open Email to Rep. Neugebauer (TX):

Dear Rep Neugebauer,
    I have read your latest Newsletter.
    You said you voted in the House to defund Obamacare while also keeping other government operations running. Congratulations! But, that is only half the issue. When push comes to shove, will you let the government shut down, or will you cave on defunding Obamacare and allow a Continuing Resolution (CR) to operate government, including Obamacare?
    You also said you were part of a group of House Republicans who wrote a letter to the Senate, urging them to take action to defund Obamacare. In part, the letter said,“Now, it is up to the Republicans and like-minded Democrats in the Senate to continue the charge to defend the American people from this disaster to their health and finances. We urge you to use all of the legislative tools at your disposal, including the filibuster, to protect America from this train wreck. House Republicans are leading the fight to control spending, stop Obamacare, and protect hardworking Americans, and it is time for the Senate to join us." Congratulations again! But again, does "using all of the legislative tools at the Senate's disposal" include shutting down the government? Or, do you expect the Senate to cave when faced with shutting down the government, if defunding Obamacare is not included?
