Shenanigans=scorched earth voting by millions of pisssed off Trump supporters.The rest of this is academic.
If the gop wishes to commit upballot and down ballot suicide, so be it.
Actually disregarding the new temporary Republicans that signed on to vote for Trump (libertarians, independents and disaffected Democrats) I don't think Trump has near 50% of the Republican votes and being that this is the Republican party some might say that Trumpkins are after hijacking the GOP.
Now I know that the GOP could use more members like the types mentioned above but Trump should do more than pay lip service to GOP ideals and should Trump get close to becoming the candidate I am interested in seeing what type of "deal" Trump makes with the party and whether or not it pisses off his base.
