Why do you give a damn..
Because, while I couldn't care less about the survival of the Republican Party, I care quite a lot about the survival of our free republic.
If the formerly grand old party has to go the way of the Whigs to save the republic, great. If someone can find some way to use the old jalopy in the service of saving the republic, without the continued co-opting, dissipation and misdirection of the conservative strength which is the only hope for the country, fine. I'll support them.
We can survive without the Republican Party. We cannot survive without the republican principles that the Republican Party once represented.
