WRAL reports: A new cable television spot by Senate Leader Phil Berger is spurring renewed speculation about whether he’ll run for U.S. Senate.  Berger has toyed for months with a possible run in the 2014 election, but had been putting off a decision….Berger’s new television ad highlights the issue of requiring voters to show ID at the polls. “Shouldn’t you show a photo ID to vote? Liberals like Obama and Kay Hagan say no,” intones an announcer during the 30-second spot. “Now, thanks to Phil Berger, voters must show a valid photo ID to vote.”
