The GOP is certainly not dead. The party controls the Congress, the White House, most state legislatures AND 34 of the 50 Governors are Republicans, just 15 are Democrats. That said, the Republican establishment could be losing its influence and Trump's base voters are looking for voters with a more pro working class bent. Breitbart News, lead by Steve Bannon is pushing candidates who support tougher immigration laws, a border wall, oppose many trade deals, foreign wars AND is less corporatist. For some reason the pro war, open borders, anti working class, corporate shills are acceptable to the mainstream media but the pro working class nationalists are to feared. Um no.
