Always support the most rightward viable conservative in every race. That's the Buckley Rule. In the Bevin/McConnell primary, Bevin is the choice.
In the General Election, Bevin is the choice in a Bevin/Grimes matchup.
In the General Election, McConnell is the choice in a McConnell/Grimes matchup.
In each of those three scenarios, the most rightward viable conservative wins.
Never vote for the Democrat, and never stay home and pout on Election Day because you don't like the Republican.
Well, you have your philosophy and I have mine. This election, if the choice is between Lindsey Graham and a Democrat, I’m voting democrat because I believe it’s the fastest way to grow true conservatives.
