Washington ? President Bush says if Congress doesn’t permit offshore drilling to increase U.S. oil supplies and possibly ease gasoline prices, lawmakers should not expect voters to support them in November.

In his Saturday radio address, Bush said experts claim the Outer Continental Shelf could eventually produce nearly 10 years’ worth of U.S. oil production. Yet while record fuel prices have focused more attention on increasing domestic energy production, experts also note that lifting the congressional ban on offshore drilling wouldn’t produce more oil for five to seven years.
