Well, yes

via TPM:

“Under the proposed law, concealed handgun licenses would be acceptable forms of photo ID, but student IDs would not,” Holder said, referring specifically to the voter ID law passed in Texas. “Many of those without IDs would have to travel great distances to get them, and some would struggle to pay for the documents they might need to obtain them. We call those poll taxes.”

Well, yes. Unless you're handing the id out for free, you're charging people to vote.

When I got my passport, I had to pay for it - and for the birth certificate needed to get it. I had to pay for my driver's license, and I'd have to pay for a state identification card. And in all cases they take time and travel to get, and those aren't free, either.

But I haven't had to show any of those things to vote. My voter card was free... but it's not photo id, is it? (No, for those of you who don't live in Maryland, it's not.) When you make people buy something in order to vote, it absolutely is a poll tax.
