I'm far from an expert in Texas election law, but here is what I found in a quick Google search[1]. In order to get an Election Identification Certificate you need to go to a DMV office during business hours with a proof of citizenship and a proof of identity. It sounds like the existence of this ID is redundant if you need ID to acquire it. It almost seems designed solely to counter people when they complain voter ID laws are the equivalent of a poll tax.
Why do you need to validate citizenship when issuing a voter ID if citizenship was already validated when registering to vote? That seems like a completely redundant requirement that is only put in place to make it slightly more difficult to acquire said ID.
I don't think citizenship is actually validated when you register to vote. I live in California and all I had to do was go on their website and check a couple boxes and fill out a form.
In several areas it is permissible for residents to be registered to vote in municipal elections etc. In some places, the local government has made efforts to get those who are neither legal residents not citizens registered for local elections. In those locations, enforcing a requirement to validate citizenship when availing onesself of the privileges thereof (e.g. voting in federal elections) makes sense.
It is very easy in the US, especially in either very urban or very rural communities. If you don't drive on public roads and are already established in life with a job or bank account, you probably don't actually need an ID for much in your day to day life. Even activities that we normally think of as requiring an ID like traveling on a plane are possible without an ID if you are willing to jump through some hoops.
