Obtaining a new first-time passport for the sake of upcoming voting is the problem.
The passport requirement hurts married women who’ve changed their names. Women are more likely to vote democratic (56%). It took me 7 months to get a passport due to name hassles (and hours of time off work).
Also, please see this post from the thread dedicated to the proposal.
All the GOP needs to do is close passport offices in blue areas. Mission accomplished.
