There is nothing inherently conservative or liberal about process questions like this.
'Is it according to the rules?', that's the question.
Alan's run is according to the rules. He is a resident of Illinois.
Conservaitve respect the Constitution and the intent of the founders in its writing. Conservatives understand there had to be a reason for writing a residency clause, Conservatives will respect that reason and not carpetbag.
Keyes has chosen the path that is not conservative.
The question is "is it according to the intent of the rules? Or is it someone finding a loophole in the exact writing of the rules?" And the answer is Keyes is clearly violating the intent, and shame on him for it.
