Sane/Non-Trumpist Republicans - why are you still Republicans?

[TPIG]

  I'm still a Republican because the Republican Party remains the best vehicle to promote the ideas/principles that I believe in, such as free-market economics, a strong and globally present military, and a defense of family values. The grotesque actions of people like Roy Moore don't make the validity of the previously mentioned principles suddenly moot.

  What else should I do? Join the Democrats? They continue to move leftward and leftward, and don't represent me on nearly any issues. Join the Liberatarian or Constitution Parties? Then none of the people I support would ever be elected, and my principles would never be implemented.

  I'm disheartened and angered by some of the trends in my party, and I understand that my brand of conservatism is not currently the "in" brand with much of the Republican base, but I'm going to stick with my party and do my part to help turn it around.
