I mean the poll itself is pretty telling. The majority of independents, liberals, libertarians and conservatives have no problem with it. Only people who are just partisan hacks are stead fast against or for it. Those of us with no agenda just think it is a good idea with the proper limitations so it does not become a burden. Like the article I posted said of the 2008 election "those affected by ID laws (could not vote) were a fraction of a percent." Not 5,000,000 people as the report that "guessed" at the number reported in 2006.
So here you have a study vs the actual election and the election proved that states with ID laws had no problems at all. It also shows without a doubt the effects on voter turnout were "negligible" at best.
