From your link:..."No Congressional Representative has drawn up a list of articles of impeachment and proposed them to the Judiciary Committee."
It's one thing to say that President has committed impeachable acts (the undeclared wars against Libya and Mexico (Fast and Furious), use of the IRS against political opponents, failure to enforce immigration laws, work requirements for welfare, his ACA waivers), and another thing to call for the House to impeach. Republicans would need sixty Senate votes to convict, or it would just waste time.
Media impeachment talk serves to rally the devout.
