U.S. President Barack Obama is pushing in his weekly radio and Internet address for Senate passage of his nearly $450 billion jobs bill as senators prepare to vote Tuesday on moving to debate on the measure. President Obama also asked listeners to Saturday\'s address to tell their senators to support the bill. President Obama said the bill \"can help guard against another downturn here in America.\" \"But if we don\'t act, the opposite will be true,\" the President said. \"There will be fewer jobs and weaker growth. So any senator out there who\'s thinking about voting against this jobs bill needs to explain why they would oppose something that we know would improve our economic situation.\" \"The proposals in this bill are steps we have to take if we want to build an economy that lasts; if we want to be able to compete with other countries for jobs that restore a sense of security for the middle-class,\" President Obama said. \"There are too many people hurting in this country for us to simply do nothing,\" he said. \"The economy is too fragile for us to let politics get in the way of action.\"
