The average politician doesn't need Secret Service protection. Of course "...someone sent on a mission with a wig to try to shove a fake award from a fake corporation into Obama's face " would be detained and investigated....and this would and will be true no matter what party any future president is from.

The rules are and were different when Obama was merely an early 'candidate' seeking the nomination. It is perfectly reasonable for candidates to have security people watching their backs, but the attitude of the folks guarding Paul and Sharron Angle, etc. is WAY over the line. Extremist political operatives with documented weird ideas WILL get extra attention, and need to screen their bodyguards as well, if not better, than their stalkers. Allowing thugs to 'protect' you gets thuggish results.
