Washington ? The post office is renewing its drive to drop Saturday delivery — and plans a rate increase — in an effort to fend off a projected $7 billion loss this year.

Without drastic action the agency could face a cumulative loss of $238 billion over 10 years, Postmaster General John Potter said in releasing a series of consultant reports on agency operations and its outlook.

“The projections going forward are not bright,” Potter told reporters in a briefing. But, he added, “all is not lost … we can right this ship.”

Sen. Tom Carper, D-Del., chairman of the Senate subcommittee with oversight authority over the Postal Service, called on Congress to give the post office the flexibility to deal with its future needs.
