I'd suggest "Democrat" :) We might not agree with libertarians 100% of the time, but we're not lunatics, we're with you on social issues, not actually that far

I'd suggest "Democrat" :) We might not agree with libertarians 100% of the time, but we're not lunatics, we're with you on social issues, not actually that far economically, and we approach problems with the intention of solving/ameliorating them, rather than using them as social dog whistles. It beats hearing rhetoric about small gov't and then getting Medicare Part D (absolute budget disaster - and obamacare reduces the projected medicare deficit, for those keeping score at home)
