Some are working to establish a viable conservative party.
Everything starts someplace, and why not when 2 radical liberals are the only choice?
Reclaiming the Republican party is the more practical and direct route to conservative power. A conservative third party only advances the leftist agenda, numerically speaking (e.g. Ross Perot).
Meanwhile, our God-given freedoms are tottering on a dangerous precipice. Political differences become irrelevant when a corrupt leader such as Obama holds the Constitution and the Rule of Law in absolute contempt, and ignores or circumvents both at every opportunity.
