The only argument I see is that a uniform statewide standard is preferable, which is probably why Corbett and others object.
So let the state set the standard and order the counties to conform to it. In the meantime let election monitors scrutinize any photo ID presented.
That's my opinion on the matter. Now, what do you suggest should be done to address Montgomery County's decision to issue photo ID cards, given Governor Corbett's decision to take no action?
No, it isn't. It's a method of rendering the requirement of a law against vote fraud a nullity (or worse) by allowing the premiere perpetrators of vote fraud in the Commonwealth a license to print "voter ID's."
The fact that Corbett has taken no action doesn't change that fact.
But that is a political matter, not a practical one. The practical concern is that election monitors you're placing so much faith in will have nothing to "scrutinize." Republican and third-party lawyers need to be present when these ID's are produced, and have full access to the process. No Judge of Election will be able to challenge fraudulent IDs once issued. Think for a second: How would it even be possible?
The only remedy left is a legal one: to challenge the issuance of a public document by a private party, or, if under public supervision, that does not permit full transparency under PA's sunshine laws.
