The Awful Truth
The heart of the American system is voting, democracy is dependent on it. Now there are restrictions, impediments, intimidation, threats and all manner of despicable shenanigans going on, it is widespread wherever the polls are close. More so it happens where black people might outvote white people, or even where democrats might outvote republicans.
It is inexcusable, often undertaken by state authorities by more or less subtle stratagems. One is simply restricting the number of polling booths in black neighbourhoods causing enormous waiting times, huge queues. Then there are requirements imposed on proving your identity, residence qualifications etc and right to vote. In Georgia, S Dakota, Pennsylvania and all over this is ongoing right now.
