Washington, D.C. ? Republicans on Saturday blocked the Senate from considering a bill next week that would nearly double federal aid to help the poor pay heating and air-conditioning bills.

Although a dozen Senate Republicans support the measure, most voted with GOP leaders who would rather spend the time trumpeting their call to expand offshore oil drilling before Congress takes six weeks off for vacation and the presidential nominating conventions.

Democrats needed 60 votes to substitute the measure on heating and air-conditioning aid in place of the debate on an expansion of offshore drilling championed by President Bush and GOP presidential candidate John McCain. They got 50 votes Saturday, with 35 Republicans voting against changing the topic.

“Do we vote to keep the old, the sick and kids alive when the weather gets cold or very, very hot, or do we spend money on people who make huge campaign contributions? That is part of what this debate is about,” said Sen. Bernie Sanders, an independent from Vermont.
