Trump may win, but like you I see the congressional Republicans getting destroyed in November. They have done absolutely nothing to stop BiteMe and have helped his Marxist agenda substantially.
Enough of the Republican base has had it with the never ending betrayals by the GOP establishment and best guess 5-15% of that base will say to the GOPE got to hell come November and not vote down ticket. Even at a 5% loss in it’s base, that will destroy the congressional Republicans chances in November. Those lying, backstabbing bastards have betrayed conservatives time and time again since 1989 and are utterly clueless to their lack of character and to the fact they are hated now by their own voters as much as they hate the Democrats.
When they lose the GOP establishment has no one to blame but themselves.
Populist landslide after populist landslide, with the correct promises (law and order, nation > ideology, traditional values > nuttyness, border control, privilege the native population, etc), every single time, sold out and betrayed by the Party, by now with threats of prison for Boris Johnson and Donald Trump (unthinkable in the Thatcher/Reagan years), and, for the next act, collapse of the offending parties into tiny factions in the elected Houses of Commons and Representatives.
I hope all you followers of the FR Imaginary Republican Party are ready for the next act, because in the UK and the US, it's right around the corner.
I will vote for Trump but NOT ONE REPUBLICAN down ticket.
I will NOT vote for Mark Green TN 7th or Sen. Marsha Blackburn this fall .
