The Trump referendum: Possible lessons from 2018 midterms

Tuesday’s election results could prove to be historic. There are more women running for office than ever before, early voting totals are shattering midterm records and Democrats are working against the odds to take back control of the House.

ABC News’ Political Director Rick Klein and Chief White House and Washington Correspondent Jon Karl spoke with Deputy Political Director MaryAlice Parks and Senior National Correspondent Terry Moran about what to expect on Tuesday on this week's Powerhouse Politics Podcast.

Topics like health care, immigration and tax reform have dominated debates and national rhetoric. The true test, though, will be if Democrats can garner enough support for voters to show up at the polls.
