We need to attack republicans but not attack Conservatives, there is a huge difference between the two these days.
The Republicans couldn’t sell out conservatism without the connivance of the vast majority of those who are known as “conservative” “leaders.” Follow the money.
This means we can't attack them. Criticize them yes, withhold support and run primary opponents sure, but no name calling and avoid burning bridges.
This also means we have to actively and vocally support them at times. If we don't they can safely ignore us and marginalize us.
And while there are some things we cannot compromise on -- i.e. the Constitution -- there are other things we can and should.
