As it has been so frequently pointed on this forum Libertarians are not Conservatives.
Voting Republican does not advance my agenda. Voting Republican rewards Republicans for making government bigger and intrusive. It says to Republicans, "I like your prescription drug program. I like your interventionist foreign-policy. I want stricter enforcement of existing gun-control (but not the repeal of any gun-control). I want the government to continue to meddle in education and health care. I want to preserve Social Security."
Your best bet is to infiltrate the Republican party, run your candidates under the Republican banner for the lower offices allowing them to develop campaign skills and get name recognition.
Libertarians neither need nor want any help from Republicans. We want Republicans to simply continue doing what they've always done. That's all the help we need.
...you can't understand that we can't roll back 50 years of Socialist advances overnight!
Oh, but we can roll it back overnight. We need people with integrity like Ron Paul who will vote consistently against big government.
...you help the Socialists make more advances?
The last Republican president to preside over a reduction in the federal budget was Warren G. Harding 80 years ago. Since then we've had 9 Republican presidents all of whom have made government bigger.
Republicans held a majority of seats in both Houses of Congress from 1995 through 2001 during which time the federal budget grew from $1.4 trillion to $2.1 trillion. Were they working to roll back 50 years of Socialist advances?
