Does This Mean That Photo ID Requirements to Buy Firearms Will Also Be Tossed by Justice Dept.?

Apparently half of Texas' Hispanic registered voters (meaning they are supposedly here legally and U.S. citizens) don't have Photo IDs and therefore would not be able to vote under Texas' new voter ID law.  Eric Holder says this means Texas' new law disproportionately affects Hispanic voters and is therefore unconstitutional. So, does this mean Justice is now going to stand up for the rights of those Hispanic citizens to buy firearms and throw out ID requirements for such purchases?
