Um, sorry, but Trump does NOT owe his victory to Sessions! He owes it to the people who voted for him! I didn’t vote for Trump because of Sessions.
The issues of immigration and trade along with protecting the American worker are what won it for Trump. Sessions 2014 article Becoming the Party of Work provided the template for victory. And the move of Steve Miller from Sessions senate staff to the Trump campaign was key. Miller wrote many of the speeches including Trump’s inaugural address and his Warsaw speech. Sessions early endorsement gave Trump a leg up on Cruz.
