"As the unemployment rate climbs, President Barack Obama is trying to make the case that his health care overhaul would create jobs by making small business startups more affordable. Dismissive Republicans blamed the continuing job losses on Democratic policies and said the presidents health proposals wont help. In his weekly radio and Internet video address Saturday, Mr. Obama linked one of his biggest challenges - joblessness - with passage of far-reaching changes to the nations health care system. If aspiring entrepreneurs believe they can stay insured while switching jobs, President Obama said, they will start new businesses and hire workers. The unemployment rate rose to 9.8 percent in September, the highest since June 1983, as employers cut far more jobs than expected. The government reported Friday that the economy lost a net total of 263,000 jobs last month, from a downwardly revised 201,000 in August. All told, 15.1 million people are now out of work.
