You might want to see what people are actually saying. The problem with ID checks is that there are barriers to entry which are conspicuously not evenly distributed. If you live in a big city, sure, it's easy but there are a lot of people around the country who have real challenges getting to the closest DMV (which can be hours away after closures and poorly connected to transit), coming up with the various paperwork establishing their identity (e.g. think about a newly-widowed 80 year old whose husband's name was on the mortgage, all of the bills, etc.), and non-trivial amounts of money.

I really wish that someone would seriously propose a voting reform act which would basically be the national equivalent of “motor voter registration” except for anyone, at no cost, and either with widespread offices or free transportation (to cover the poor, old, blind, etc.). Get rid of every possible excuse for not having ID and then we can clean up so many screwy processes which rely on a patchwork of paperwork to handle different situations, no two agencies with identical requirements.
