A Pew Research poll shows that proposals to require voters to show photo identification before being allowed to vote draw overwhelming support.

By 77% to 20%, registered voters favor a requirement that those voting be required to show photo ID, the survey shows. Opinion about this is little changed from six years ago, when 80% of voters supported voter photo ID requirements.

Several states have enacted strict photo ID voting requirements, but there have been court challenges to many of these laws. Last month, a Pennsylvania judge blocked enforcement of that state's voter ID law, says the survey.

In a national survey of 1,263 registered voters, conducted Sept. 12-16 by the Pew Research Center for the People & the Press, nearly all (98%) say they are confident that they have the identification they will need at the polls on Nov. 6.
