Jim Geraghty of National Review and Greg Corombos of Radio America shake their heads as Democrats win another high-profile special election.  By itself, it may not mean much, but Democrats have won a string of races where Republicans were expected to be competitive or heavily favored.  Wisconsin Gov. Scott Walker is openly concerned about a "Blue Wave" in 2018 and Jim and Greg discuss why he's right to sound the alarm.  They also sigh as the Trump administration and China swap tariffs, leading to stock market drops and higher prices.  And they shake their heads as the media go wall-to-wall with coverage of the shootings at You Tube headquarters, only to drop the story when the shooter does not fit the media stereotyp of a mass shooter.
