Conservative activist groups are orchestrating a coordinated campaign to pressure Republican Members of Congress on a key issue for them at town hall events this summer. But all of that effort is going to defund Obamacare, while the Senate passed immigration bill is being completely ignored.

“At the bottom of this post you will find a list of congressional town halls for the next week,” RedState co-founder Erick Erickson wrote Friday, “Stay focused. Show up and confront your Congressman. Tell him if he votes to fund Obamacare, he cannot really say he is fighting against it.”

No mention is made of “immigration” or “amnesty” anywhere in the post.

The same is true of FreedomWorks, which has taken the “extraordinary” step of including the defunding of Obamacare on their online scorecard.

The Senate Conservatives Fund, which fought amnesty in the Senate, is also asking its members to support efforts to “Defund Obamacare” as well as to “Defund the I.R.S.,” but amnesty is not listed as a priority for them in August either.

Heritage Action Fund, which has fought amnesty in both the House and Senate, is not messaging on amnesty in August either. Instead, they are also promoting a campaign to defund Obamcare, including nine town halls across the country, beginning August 19.

One reason conservative activist groups may be completely ignoring amnesty, is because Senate Majority Leader Harry Reid, D-Nev., has not even sent the Schumer-Rubio amnesty bill, S. 744, over to the House. There simply is no existing House legislation for conservative activists to rally against.

That may be because S. 744 is unconstitutional. Talking points distributed by House Judiciary Committee Chairman Bob Goodlatte, R-Va., explain:

The Senate immigration bill is a revenue-raising bill, which makes it unconstitutional. Specifically, the bill contains a wide range of effects on federal revenues, including changes in collections of income and payroll taxes, certain visa fees that are classified as revenues, and various fines and penalties. Language in the U.S. Constitution requires that any bill that raises revenue, also known as a tax, must originate in the House of Representatives, not the Senate.
