Why does OBAMA or any democrats say "WE INHERITED THIS ECONOMY"?

more of his slick talk that does not reflect the facts. Obama's voting record for the who;e time e was a U.S. Senator is public record,and checking it was a priority of mine before the election (in fact I thoroughly researched ALL the candidates) Obama voted with his fellow dems.97% in05 95%in06 and 99% in07 whiich means Obie voted for the same policy's he's crying about "inheriting" from Bush !
