Quoting from the wikipedia article here: https://en.wikipedia.org/wiki/Voter_ID_laws_in_the_United_States https://en.wikipedia.org/wiki/Voter_ID_laws_in_the_United_St... Research has shown that the type of voter fraud that would be prevented by voter IDs is extremely rare; research is mixed as to whether voter ID laws reduce overall turnout or minority turnout; and research has shown that Republican legislators in swing states and districts with sizable black or Hispanic populations push the hardest for voter ID laws. While I personally suspect that both republican and democrat concern about voter ID laws comes from a (mostly overblown) fear of being disenfranchised- I wouldn't really call it common sense any more than it's common sense to believe that the people who aren't going to vote for your policies shouldn't be able to vote at all.
