1) I never said they were... the point is.... people have to have ID's to do a lot of things in this country. Pretending that it is such a huge inconvenience to get an ID for voting purposes is simply NONSENSE.
Voting should have as few inconveniences as possible and any inconveniences should be absolutely necessary. I don't give a damn if flying is inconvenient.
2) All of those commercial transactions ask for ID to help avoid what? FRAUD (with the exception of airlines where it is done to make sure u not a terrerist)
Even assuming that you are correct that these commercial transactions require ID to avoid FRAUD, that's because fraud is a real problem that requires some sort of remedial measure. Voter impersonation is not a real problem.
