People in Indian who do not have Identification can votes with a probitionary ballot. Personally took an individual the day after the election to get her ID. Then we grocery shopped at a larger store then she normally goes to (better prices) and stopped by the court house to trigger her votes.
AND she was a liberal democrat.
There are many who will help if it is truly needed.
Did you mean provisional ballot?
Typically provisional ballots only come into play during an extremely close race. And they can usually be challenged.
