AUSTIN, Texas - In his radio and TV ads that are blanketing Texas, Barack Obama claims a chief executive can make more money "in 10 minutes" than an ordinary worker makes in a year. Obama wants to end the Bush tax cuts for the wealthy, enact a national health plan, offer a $4,000-a-year tuition reimbursement in exchange for national service, and have the government intervene to prevent home foreclosures. But he doesn't want anyone to call him a liberal.
