Are the Libertarian Party and the Constitution Party alternatives to the Republican Party? I joined the Libertarian Party this year because of it's great emphasis on liberty and struct interpretation of the US Consititution. I find the Constitution Party to have similar traits though more Christian right leaning and the Consititution party could be called the true CONSERVATIVE party. I chose the Libertarian Party because of it's fairness in approaching the issues realizing that not everything can be labeled Conservative or Liberal. It seems most new converts to the Libertarian Party and the Constitution Party are former Republicans who appreciate both the Libertarian Party and the Constitution Party's attempt to strictly interptet the Consititution.
