Take "Idiot" out of the constitution?" It's on NJ Ballot

In about two weeks, on November 6,  New Jersey voters will decide whether to eliminate insensitive phrasing in the state Constitution that characterizes people with disabilities as "idiots" and "insane". The offensive language, adopted in the constitution in 1844, is aimed at barring people with limited mental capacity  from voting. 

Strange there is nothing banning anyone with "limited  mental capacity"  from running. How else do you explain all the politicians in Washington?
