On the campaign trail, a series of new polls show an increasing lead for Senator Barack Obama over Senator John McCain. Several polls show Obama ahead in key battleground states, including Ohio, Pennsylvania and Florida. Nate Silver of the polling website FiveThirtyEight.com says McCain’s chance of winning the election has dwindled down to 3.7 percent, down from 6.5 percent. On Thursday, Obama campaigned in Indiana.

Sen. Barack Obama: “More tax cuts for jobs outsourcing, that’s what Senator McCain proposed as his answer to outsourcing. He said that’s, quote, 'simple fundamental economics.' Well, Indiana, my opponent may call that 'fundamental economics,' but we know that’s just another name for Wall Street first, Main Street last. That’s the kind of economic philosophy we’ve had for the past eight years. And that’s fundamentally wrong.”

McCain was in Florida, where he continued to invoke “Joe the Plumber” to portray Obama as a “tax and spend” Democrat.

Sen. John McCain: “He believes in redistributing the wealth, not in policies that grow our economy and create jobs and opportunities for all Americans. Senator Obama is more interested in controlling who gets your piece of the pie than he is in growing the pie. You know, whether it’s Joe the plumber in Ohio or Joe over here — thank you, Joe, Joe, thank you; there’s Joes all over here, small business owners I met with this morning here in Florida — we shouldn’t be taxing our small businesses more, as Senator Obama wants to do.”
