In case you missed it, the Kentucky Libertarian Party is not pleased with libertarian-leaning Republican senate nominee Rand Paul.

A week after a come-from-behind victory over the GOP’s establishment candidate in a Kentucky Senate primary, Rand Paul is facing a possible challenge by the Libertarian Party and is shaking up his staff after comments he made about racial segregation caused a firestorm.

Despite his pedigree as the son of former Libertarian presidential candidate Ron Paul, Libertarian Vice Chairman Joshua Koch said Rand Paul has betrayed the party’s values with stands he’s taken, and they were considering finding a candidate to run for the seat.

It was a startling development that could play a role in shaping the outcome of the race in November by siphoning votes from Paul to the benefit of his Democratic opponent, Kentucky Attorney General Jack Conway. The news came on the same day that Paul named Jesse Benton, one of his father’s former aides, as his campaign manager.

It will be interesting to see if libertarian-leaning voters go against Paul if a libertarian enters the race. Paul leaned toward Republican values on many issues in his campaign–he ran as a Republican after all–and we’ve written here before that to win voters in and near the middle, Paul may have to continue walking the line between traditional Republican values and quasi and full libertarian values. Many observers say the Tea Party’s growth shows that fiscal conservancy will trump all for many voters, but that hasn’t yet been proven electorally, despite some possible evidence in recent primaries.
