Being an independent who leans toward the conservative, I would answer that the Republicans have not fielded the right candidate. The issues have not changed. It is not logical for a party that favors strict enforcement of the Constitution to bend to leftist demands that favor ignoring the law of the land.
There are valid reasons that much of the white race is angry. Diluting their voting numbers with foreign influence and those with only the handout mentality is reason enough. And ever-increasing taxes to pay for the welfare state at the expense of its retired is more than enough reason to be opposed to the liberal agenda. Change? The issues have not changed.
