It is not enough for either us or our Republican congressmen to sit on the sidelines with Obamacare's mandates ever approaching.It is time to take action.As I explained last week, Rep. Steve King has filed a discharge petition on legislation to repeal Obamacare. If he gets 218 signatures on his petition, Nancy Pelosi is forced to have a vote on the legislation whether she wants to or not.The petition and accompanying legislation are not muddied down with the "repeal and replace" nonsense — just plain and simple repeal. You know, exactly what the American people say they want in poll after poll after poll after poll.In the Republican leadership, Congressman Mike Pence has already signed the petition. House Minority Leader John Boehner will be signing it this week.That means we need to all call Congressman Eric Cantor at (202) 225-2815 and politely ask him to sign it this week too.There is no excuse for the Republican leadership to not sign this petition. In fact, as the leaders of the GOP in the House, they should go first. Their failure to do so is an explicit admission they've been lying about their desire to repeal Obamacare.Let's not muddy the waters. Let's not fight over which provisions to keep, tweak, save, or reform. Let's have our leaders listen to the American people and repeal Obamacare.We're going member by member posting their Congressional office phone numbers and having people call. The members will either sign the petition or their failure to act will be proof they are liars when they say they favor repeal.If you want more information, Heritage Action for America is spearheading this effort. It's time for the House Republicans to put up or shut up. All they have to do is sign Rep. Steve King's petition.
