I'm of the mindset that, even if one doesn't initially realize something has a negative effect, continuing to defend it once one does learn makes one part of the problem.
I used to think that requiring ID to vote made sense. However, once I learned that it has a huge negative impact on minority communities and is virtually pointless, I changed my mind.
Even the most, shall we say, concerned, websites only point to a little over 1000 instances of voter fraud...over the last 18 years!! It's unconscionable to argue for these ID measures that severely restrict certain groups' right to vote for such a minuscule problem. People who advocate getting ID laws in place need to work on fixing the problem of ease of access to getting an ID first if it's so important to them.
As far as problems with our elections, one of the other major concerns is voter access to polling places. Problems like counties shutting down many polling sites in high-minority areas, or only providing 10% of promised voting booths to high-traffic high-minority locations needs to be corrected.
