He’s ahead, so what’s wrong with waiting until mid-October?
Because of 'Early Voting', that is why! While mail-in votes from military and expats is only lightly, if any, influenced by advertising, local mail-in votes have already started in many areas. It is quite possible that an NC voter (Sept.9th) could have voted for Hillary and then regretted it after the 09/11 fiasco.
There are going to be early, in-person voting, for 3 states, Minnesota, South Carolina and Michigan, BEFORE the 1st Hillary_v_Trump debate on Monday 09/26. By the time of the 3rd debate on 10/19, it appears POSSIBLE that close to 1/3 of all votes will already have been cast!
This is my prime objection to such a broad time frame for 'early voting', it is lazy and benefits the establishment and known-name candidates. It fails to provide, an impossibility, for withdrawal of a vote based upon newer information. My personal choice would be for Federal Office voting to be limited to a 3-week time prior to the official day, but that does violate FEDERALISM so I have to take the bad with the good!
