@mysteryman,
Oh, you are ignoring quite a bit.
Compare the anecdotal, piddly nickel and dime examples of fraud you can sift around and find, with the wholesale onslaught that the GOP is mounting to subvert Dem voters, and it becomes clear that you are ignoring the forest to proclaim about the trees...
From a 2012 report by the Brennan Center for Justice:
These new restrictions fall most heavily on young, minority, and low-income voters, as well as on voters with disabilities. This wave of changes may sharply tilt the political terrain for the 2012 election. Based on the Brennan Center’s analysis of the 19 laws and two executive actions that passed in 14 states, it is clear that:
•These new laws could make it significantly harder for more than five million eligible voters to cast ballots in 2012.1
• The states that have already cut back on voting rights will provide 171 electoral votes in 2012–
63 percent of the 270 needed to win the presidency.
• Of the 12 likely battleground states, as assessed by an August Los Angeles Times analysis of Gallup polling, five have already cut back on voting rights (and may pass additional restrictive legislation), and two more are currently considering new restrictions.2

...and oh, those "young, minority, and low-income voters, as well as on voters with disabilities" that the new restrictions will impact? It just so happens that they vote overwhelmingly Democratic.
