As for me, it is not about political agnosticism, I have stances I want to see go forward, and most of them are Liberal. But I do not see Hillary being able to do that, because she tends to be the status quo. I voted for Obama because I thought he would change things... but his choices... of the ACA, instead of a Public Option/Medicare for all, etc, has soured me on the status quo. They seem to lack vision.
So if it is two lackluster status quo politicians, and one is more likable, it is like picking chocolate or vanilla. They are both pretty much "safe". Kasich is no Bush, or Trump.
