From Political Wire:
Sen. Daniel Akaka (D-HI) and Rep. Ed Case (D-HI) have impressive job approval ratings, a new Honolulu Advertiser Hawaii Poll has found, "but people who say they may vote in the Democratic primary for U.S. Senate in September give the advantage to Akaka."
Democratic primary voters favor Akaka over Case 51% to 40%, with 9% undecided.
CQ Politics: "Case still is providing Akaka with his most serious challenge since he first won the Senate seat in a 1990 special election. And the bare majority held by Akaka — whose effectiveness has been strongly questioned by Case and even some independent sources — is hardly an overwhelming confirmation for a figure who has been in Congress since his election to the first of seven House terms in 1976."
