Well again, either those people are RINOs or they may actually believe in smaller government but aren't living those values (or there are people who actually believe in smaller government like minarchists or Constitutionalists but they don't see how ancap-ism is kind of like a form of minarchy).

The people who aren't living those values but believe in them could be walked through how some policies they've knowingly or unknowingly supported could be damaging to them.
