Jim Geraghty of National Review and Greg Corombos of Radio America discuss new polling showing public perception dropping for businesses that are publicly breaking ties with the NRA, due entirely to a massive plunge in favorability among Republicans.  They also breathe a sigh of relief as Republicans in Arizona's eighth congressional district reject the frontrunner in the primary after the married minister was caught exchanging inappropriate texts with a female staffer.  And they wish the best of luck to 20 state attorneys general who argue that all of Obamacare should be declared unconstitutional now that the tax provision that saved it at the Supreme Court in 2012 has been scrapped in the new tax law.
