LOGIC:
WH was focused on the Senate all along. ( Just look at the Rallies) Because of No Name and then Flake “not running again”. This would make sense in that Senate numbers would have to be increased.
The House was a different story. Those R’s that were not “running again” that were in a sense, “allowed to leave” put that majority in serious doubt. Not to fear because as the R’s were “allowed to leave”, the D’s will be put in serious PAIN when the Sealed Indictments are finally unsealed. That and the DECLAS along with IG Report will not only have DC in a Panic but will leave the D Party absolutely CRUSHED.
The House Majority will never be in the D’s hands again. I believe this will take place before the New Congress in sworn in in 2019. This all makes perfect sense in that EO13825 https://www.federalregister.gov/documents/2018/03/08/2018-04860/2018-amendments-to-the-manual-for-courts-martial-united-states is effective come January 1st 2019.
