Facing only token opposition, U.S. Sen. Daniel Inouye appears to have an easy ride to a ninth six-year term.

The 85-year-old Inouye last month was one of two Democrats to file candidacy papers for the seat he has held since 1963. The other is 39-year-old Andrew Woerner of the Big Island.

Also in the race are Republicans Cam Cavasso, 59, and John Roco, 44; Libertarian Lloyd Jeffrey Mallan, 66; and independent Jeff Jarrett.

Meanwhile, the leading candidates in Hawaii’s 1st District congressional election have indirectly accused the other of catering to mainland interests.

In an e-mail, Republican U.S. Rep. Charles Djou lit into Democratic state Senate President Colleen Hanabusa, without naming her, for being "feted in Washington, D.C., by the insider establishment."

For his part, Djou has raised more than $309,000 from political action committees—much of it from influential Washington-based interest groups and GOP members of Congress.

"It’s pretty clear that after just a couple months, Djou’s already gone Washington and forgotten about who he was elected to represent," Democratic Congressional Campaign Committee spokesman Andy Stone said in an e-mail.
