If I am (and was, at the time of the election) relatively indifferent to Trump, can I still vote?
I think isolated incidents of fraud almost certainly occur, but I highly doubt they were enough to swing any state or be statistically significant in any way; actually, quite the contrary, the states where I would suspect fraud to occur more are probably D states anyway, so it doesn't matter too much.
That being said, from a GOP strategist's perspective, this is probably a good 'wedge issue' to push. I haven't seen any actual polling on this, so I might be wrong, but I would suspect most people would not care too much about having stricter ID requirements, and are probably not very sympathetic to those who can't meet the requirements. That's just my suspicion though, I could be wrong.
I'm not making an argument for/against; just stating it's probably a good issue for the GOP to push strategically.
