Why you would attack a Libertarian voter for not voting for the Republican party is unclear.
The only reason why libertarians and members of the Libertarian party ever vote Republican is because they feel like positives of the fiscal conservative aspect of the party outweigh the negatives of its theocon side.
Unfortunately, over the last 6 years the GOP has become less and less fiscally conservative and began catering more and more to theocons.
The GOP being expecting libertarian voters is like an unattractive, unemployed guy being upset because a girl doesn't choose to be with him.
A very inapt comparison. To have a mate is a choice. There are always multiple options, even if they're not actual at the moment. There's no such situation politics and government. The choice is between a mildly statist party and a very statist party. Ludicrously, the Libertarians seemingly would rather let the very statist party (at heart, a socialist party) win rather than soil themselves with a vote for the much less statist party. Spare me your cheap shots at the Republicans. The Libertarians are fools.
They took away votes that would have prevented the Democrats from taking over Congress in a time of war--how much clearer can one be?
