Jim Geraghty of National Review and Greg Corombos of Radio America applaud columnist Ruth Margolis for blasting liberals who demand that parents must immerse kids of all ages in politics and the social justice movement.  They also wince at the evidence Republicans may have lost congressional seats in states like California and New Jersey because they limited how much residents could use their state and local tax bill to reduce their federal tax payments.  And they react to Senate Majority Leader Mitch McConnell urging Arizona Gov. Doug Ducey to appoint defeated Senate candidate Martha McSally to the state's other Senate seat if Jon Kyl steps down before 2020.
