Uninformed people like Obama and Trump and Clinton and anyone else who says elections are rigged, do not know the process or they do (believe me, Trump does not) but they want to rile up the people to believe it is all rigged and everyone in the country hates them except for their rabid fans.
There is NO "national" huge election. Every election takes place in a COUNTY/PARISH. Think of that, your county/parish. Is
your county election rigged? If you think so, then you need to document that and go to your District Attorney and file a complaint. The District Attorney is required by law to investigate your claim/evidence. If he/she refuses to investigate, send your evidence to the State Attorney General and he/she is required to do it and will hammer your District Attorney for not doing it.
To educate yourself how elections are run in counties/parishes - your county, so you speak from knowing the laws, I encourage you to go to my thread posted yesterday:
