This is the 3rd time. The first time was in 1988 when he rar under the Libertarian ticket, then in 2008 and now
...it seems like a billion times already.
And why exactly isn't he running on the Libertarian ticket this time around since Paul is in fact a libertarian? Kinda deceitful that he uses the (R) label to get noticed when everyone knows full well he won't support the eventual GOP nominee - and nearly half his support is coming from liberal and independent crossover voters.
