You say the liberty voter. I'm guesing you mean fiscally conservative, socially liberal. Well, about a third of FR is conviced we need the people who are the other way round.
Liberty voters are (sometimes) fiscal conservatives and (sometimes) social liberals, but in either case are passionate about the government, especially the government at Washington, LEAVING US ALONE TO LIVE AS WE SEE FIT.
If we on the right cannot agree on this as a foundational principle, we will never be in the majority again.
