ABC News' Imtiyaz Delawala Reports: Alaska Gov. Sarah Palin continued the Republican ticket's attempt to tie Sen. Barack Obama to what it calls socialist economic policies, attacking in new language Obama's plans to offer tax credits to those paying no income taxes and saying that "now is no time to experiment with socialism." At an airport rally in Roswell, N.M. on Sunday afternoon, the Republican vice presidential nominee once again invoked Joe Wurzelbacher, now widely known as "Joe the Plumber," pushing Wurzelbacher's contention that Obama's tax plan sounded like socialism – a point also invoked by Sen. John McCain on Sunday."Senator Obama said he wants to quote 'spread the wealth.' What that means is he wants government to take your money and dole it out however a politician sees fit," Palin said, drawing boos from the crowd of several thousand. "But Joe the Plumber and Ed the Dairy Man, I believe that they think that it sounds more like socialism," Palin added, referring to both Wurzelbacher and a man holding a sign reading "Ed the Dairy Man" in the crowd. "Friends, now is no time to experiment with socialism. To me, our opponent plans sounds more like big government, which is the problem. Bigger government is not the solution." Palin questioned Obama's plan to offer tax credits to Americans currently not paying income taxes, calling it "a government giveaway" that would raise taxes on other Americans. "He claims that he'll cut income taxes for 95 percent of Americans, but the problem is, more than 40 percent of Americans pay no income taxes at all," Palin said. "Since he can't reduce taxes on those who pay zero, he wants the government to send them a check that's called a tax credit. And where is he gonna get the money for all those checks that he will cut? By raising taxes on America's hard-working families and our small businesses." "Obama's plans to raise taxes on some in order to give checks out to others is not a tax cut, it is more government growth and it's another government giveaway," Palin added. "Whatever you call his tax plan and that redistribution of wealth, it will destroy jobs. It will hurt our economy. And it's about time that we all called Barack Obama on it."After the Roswell event, Palin flew to Colorado Springs, Colo., where she will have a morning rally on Monday. At the Colorado Springs airport, Palin took questions on the tarmac from the local and traveling press corps, defending her charge that Obama's tax policies have socialist aspects."There are socialist principles to that, yes," Palin said of Obama's tax plans. "Taking more from a small business or small business owners or from a hard-working families and then redistributing that money according to a politician's priorities -- there are hints of socialism in there and that's why I don't fault or discredit Joe the Plumber for bringing that up, asking if that is socialism."But Palin disagreed when asked whether she thinks the $700 billion government bailout plan and bank rescue efforts had socialist aspects. "No, I do not," Palin said. "And I believe that there are those measures that had to be taken by Congress to shore up not only the housing market but the credit markets, also to make sure that that's not frozen, so that our small businesses have opportunities to borrow and that was the purpose, of course, of that part of the bailout and the shoring of the banks."
