Dems fund the Libertarian candidates, also. Murdock (put a sock in his mouth) was challenged by Libertarian candidate Horning (http://www.horningforcongress.com/ )and lost by the votes Horning picked up.
It’s a winning strategy for Dems and I expect to see it widely used in the 2014 Senate races. Got McAwful elected in the Virginia gov race.
The “Clintonian plurality” win...cringe...
