BIG SPENDERS. Barack Obama may have outspent Hillary Rodham Clinton 3-to-1 through most of the Democratic primary, but John McCain is not going to let that happen in the general election. Evidently, McCain - the presumptive Republican nominee - raised $21.5 million in May on top of another $53.6 million raised by the Republican National Committee. Obama has not released his numbers for may yet, but in April he scored $37.3 million. Our economy is in the dumps and these two are waisting good money on commercials and yard signs. There has to be a better way!
