Studies have shown that states that require photo identification in elections have little to no significant difference in voter turnout or fraud. “In [a] 2008 survey, three out of 2,564 respondents said that they tried to vote but were not allowed because of voter ID, a fraction of a percent.”
Here lets repeat that....
have little to no significant difference in voter turnout
Does it need to be any clearer? The study from 2006 was talking about the 15 states AT THE TIME that now have SCOTUS approved voter id laws, period. I don't know what these "new" voter id laws coming into affect you are talking about.
