Of course not. Just like the Republican Party drove away other groups of voters purist conservatives are determined to drive away groups of voters that may have enough overlap on certain issues to get their votes. Who needs the libertarians? Its better to have them vote for somebody else. And who needs the young people? Let them vote for somebody else. And who needs minorities, its more fun to rail about Hispanics than figure out how to keep strongly conservative Cuban Americans (for example) voting Republican.
Instead we should concentrate on only putting forth candidates who hold a narrow and specific set of beliefs, and only try to appeal to voters who are 100% in agreement with those beliefs. Lets find candidates who think that women don't get pregnant from rape. They seem to appeal to a broad spectrum of voters.
The bilge posted in this thread along with the voter fraud in Republican primaries against Ron Paul help explain why so many stayed home.
Since libertarian Republicans are primarily focused on economics, the way to win them back would be for R's in Congress to make genuine efforts to cut spending.
The last polling data on this suggests almost 70% of “likely voters” want this to happen.
I fully expect those R's who hate libertarians will continue to push the party toward some ideally level of ideological purity.
But each time these people attack, they make it a bit harder for R's to win elections in 2014 and 2016.
I often wonder if such people are actually D's doing their best “divide and conquer” against conservatives and their would-be allies.
