Politicians have no more right to security than anyone else. If it is a good idea for them to protect themselves with guns, the everyone has the right. President, president-elect, and party nominee are not positions above citizen.
Of course politicians are in "positions above citizens."
We specifically elect them, and want them, to be in "positions above citizens."
You know ..... we have them debate and create laws which ordinary citizens do not do.
We allow them to make decisions in our courts (judges, justices) that ordinary citizens do not do.
We give them the authority to travel to other nations, and to discuss treaties, trade, allegiances and war ... things that ordinary citizens do not do.
So stop pretending that these people don't require more protection than you and me, because they do.
No one should be offended (or surprised) by the fact that their life
IS more important than yours and mine.
