That argument doesn’t have a great deal of merit when you look at the Indiana Senate race numbers - Richard Mourdock was not moderate. The Libertarian candidate got a rather huge chunk of the vote there for a third party candidate, and enough to have given the seat to Mourdock with the current numbers coming in.
No, that just shows you how weak the republican brand is.
A libertarian shouldn’t be able to get more than .2% of the vote.
Like I said, Republican Party is a failure just like the Wigs.
