Really? I keep hearing that from the racism-sexism-homophobia history crowd but nobody ever seems to be able to give me a citation. So I ask you again - where does it say in either the federal Constitution or any of the State ones that the right to vote was restricted to white people? I'm genuinely curious.
What is your point? Obviously they didn't have the right to vote. If they did, they wouldn't have needed a constitutional amendment.
If you need more proof than that, I suggest you use Google.
