You sound sooo PC. There is no special Presidential way to speak. You are trying to control speech style that you do not like.
Attacks on Bush are meaningful because some voters could be swayed by the Bush lying attack ads and vote for one of the other candidates thus possibly affecting Trumps overall vote count. Bush is in the race and if he attacks he needs to be attacked back, not ignored. We have seen this before and it does not work.
Try real hard to understand - nobody said that Trump couldn’t attack anyone, nor that there is a special Presidential way to speak - except that that speech should as much as possible be measured, reasonable and relevant to the issues - and avoid as much as possible ad hominem jibes, self-absorbed braggadocio, childish grimaces, and schoolyard taunts - we’ve had going on eight years of such divisiveness and incivility under Obama, and we don’t need it for another four years under some other president - that’s not PC, it’s respect and responsibility toward those with whom and for whom the president serves.....
