An Answermug pal says that pols get death threats because there are radicals on both sides of the aisle. Who gets more death threats?

Republicans or Democrats? I wonder if that is ever kept track of somewhere. Getting a death threat from some wacko nutjob just because you espouse a cause or support someone of whom said nutjob disapproves is insane. All death threat senders are wacko nutjobs. Period. :(
