But a "free" card , if it involves supplying a photo from photo booth thing, is not entirely free.
If you're really poor, minimum benefits poor,
Or you would have to travel to a higher town to find a photo booth
Or, you have extremely restricted mobility,
Or, you have issues that mean getting the photo, filling in the form, supplying some other ID(which most forms require)doing these things sufficiently far in advance, then registering to vote(already less easy than it used to be)
Top of my head I can think of half a dozen people I know, for whom these thing would be difficult enough that they'd likely be defeated .
I suspect that it's a hugely disenfranchising measure, to crack a barely existing but.
But, because those in politics and the media can't imagine what it's like to be really poor, heat or eat poor, or disabled, or have mental health problems, well, not really affecting people like us, so no problem, eh?
