From Grover Cleveland to Barack Obama e discuss that concept of 'coattails' - the impact of a Presidential win on his party's hopes for Congress. Each Presidential election it is asked, can downticket races grab on to the President's 'coat'? - this one goes back to the days you might see the POTUS in a coat - can they get in on his win. What if he doesn't win?
Will the Presdient have them? It's a complex subject as its only in modern times that all states conduct congressional and Presidential elections at the same time.
Will the President even win and if he doesn't win - can his party take the House anyway, can the parties 'switcheroo?'
Or: Can you have coattails with no one in the coat?
