Jim Geraghty of National Review and Greg Corombos of Radio America applaud White House Chief of Staff John Kelly for blasting four cabinet secretaries on ethics matters ranging from travel to office decor.  They also shake their heads a day in advance of the special congressional election in Pennsylvania, as the Republican appears to be running a very weak campaign and the Democrat believes life begins at conception but opposes late-term abortions.  And they get a kick out of Massachusetts Sen. Elizabeth Warren refusing to take a DNA test to resolve the controversy over her claims of Cherokee ancestry.
