If what we believe in is a minority of a minority party...then this whole debate is moot.
We are already lost. So why bother?
It isn't that we are a minority, but that there aren't enough Conservatives elected to Congress. Our Congressional leadership is RINO and will remain RINO until one of two things happens:
1)Enough Conservatives are elected to force a change in leadership.
2)We must lose, and lose big in an election... If that happens the party leadership generally must step down and new leadership is appointed, as the loss is taken as a vote of no confidence. Since the RINOs are in leadership, the Conservatives would take control.
Whether voting out of principle or because you are fed up with the party's direction, the intent should be to vote Conservative rather than "any ol Republican will do". If we continue to elect people who do not believe what we do, what will be the inevitable end?
