No, the GOP will not lose the House. Not even if Trump loses in a landslide of biblical proportions.

UPDATE: 1-Nov-2016

A recent Cook Political Report (among other articles) excited Democrats and terrified Republicans by invoking the specter of a wave election flipping the House of Representatives majority control - "House Republicans Staring Into the Abyss: 10 Ratings Changes Favor Democrats":

"So many assumptions have been wrong this cycle that it's difficult to be definitive about another: that the House majority won't be in play in 2016.  Republicans are sitting on their largest majority since 1928 - 247 seats to 188 - meaning Democrats would need to pick up 30 seats, a daunting challenge given the GOP's immense redistricting advantage and the vaporization of swing districts. But all cycle, Democrats have daydreamed about Republicans nominating an extremely polarizing presidential candidate, and suddenly it's almost certain they will get their wish...   if November does turn into a Democratic rout, it's impossible to know just how bad it could get for Republicans sharing a ballot with Trump or Cruz."

The primary evidence offered by columnist David Wasserman was a shift in the Cook Report Rating for 10 seats (5 D, 5 R) with each seat ratcheting one notch in the Democrats direction. But, there is far less here than meets the eye.

United Coalition of the Divided - 2016 Edition

UPDATED: 7-Nov-2016

The Dividist initiated this exclusive club during the 2008 election cycle and recycled it in every federal election since. It was an ignominious start, with the Democrats seizing unified control of the federal government. The 2010 edition was barely posted in time for the midterms among much angst and gnashing of teeth. Can't complain about the result though, as divided government was emphatically restored. We managed an earlier start on the 2012 membership drive, and that worked out fine with the reelection of Barack Obama and divided government. In 2014, it was just a question of how divided we were going to get. The Democrats accommodated by digging themselves an even deeper hole in Congress, much to the delight of our 2014 Midterm United Coalition of the Divided. 

Now it's 2016. We know why we should vote for divided government. We know how to vote for divided government.  We just need enough of us to actually vote for divided government. 

This cycle we'll be voting for a new President with the Republicans in majority control of Congress. At the time of this writing, Republicans and Democrats are focused on eating their own. Soon Democrats will realize that a divided government state is the best they can hope for in this cycle. As always, the Dividist will welcome with open arms all disingenuous, insincere, and hypocritical partisan Democratic and Republican Party pretenders to the 2016 United Coalition of the Divided!

Membership is open to anyone writing anything in any form in any media in a vaguely positive way on the subject of divided government. New recruits will be added to the ranks, updating this post and blogroll from now until the 2016 election.
