Safeguard American Voter Eligibility (SAVE) Act - End of Democracy or Its Savior?

See this thread and see how hard it was for @Czarcasm to get a birth certificate from Guam:

Possible Real ID problem?

So I am following procedure to get my birth certificate from Guam, which means I have to snailmail a $5 money order to them and wait. The trouble is that this birth certificate will have the last name from my first father, which will definitely not match up with the last name I have used for most of my life which I got from my second father. What further step(s) might I have to take to get my Real ID?
