The euphemistic well the Republicans have referred to is already poisoned and Boehner just did it.

(Reuters) - Legislation (click here) allowing the construction of the Keystone oil pipeline from Canada to the U.S. Gulf of Mexico, repealing Obamacare and reducing the nation's debt are at the top of Republicans' 2015 agenda, House of Representatives Speaker John Boehner said on Thursday.

In his first news conference since Tuesday's congressional elections that saw broad Republican victories, Boehner also said that if President Barack Obama unilaterally loosens some immigration regulations, he will "poison the well and there will be no chance of immigration reform moving" in the next two years....

The Republicans are back to their old tactics of obstruction. The country will once again face brinkmanship on the debt ceiling and budgets. Nothing has changed.

I suppose Boehner actually believes coercion will work. In case he doesn't recognize it, those statements are THREATS. That is a ethnics violation.
