The House has “the sole power of impeachment” (Constitution Art. I, Sec 2)but the Senate has the power to remove him from office based on his impeachment. Clinton, for example, was impeached but the Senate voted to let him stay in office. First step is impeachment by the House which is doable.
Thank you for mentioning those points. I could be mistaken, but I think that groups like NBRA actually want Obama out of the Oval Office. The problem is that impeachment by HoR will be the equivalent of reprimanding Obama with a wet noodle as it was with Clinton. In other words, all that impeachment by HoR will mean to Obama, imo, is that he will probably have less time to spend on the golf course.
