Why did democrats do worse in the 2016 election when people actually had to show their face to vote?

Because cheating and whining is the only thing they know

Art........you sound clueless about elections. States have mail in voting UPON REQUEST. In the past, states didnt mail voting applications to anyone on a voter roll (some of those people being dead) like in 2020. Do some research on the topic before responding and sounding so ignorant.

You are really clueless about elections.  Many states have had no excuse mail in balloting for decades.  All states have mail in for people who will be out of state, and for the military.  GA has had the "souls to polls" Sunday voting for a long time too.  I showed ID when I registered to vote 20 years ago.  I've not showed ID ever since. 

It's best to educate yourself on a subject before opening your mouth so you do't look ignorant. 

You had to show your ID.

NOW you can just do a mail in ballot without showing who or where you are from

Could be some people are not honest.  Like moved out of state but got that mail in ballot.

The media managed to mention Trump a million times more often than the front runner, Bernie Sanders.
