(CNN) -- Democratic vice presidential candidate Joe Biden ripped into recent comments by his Republican counterpart that suggested that some places in the U.S. are more "pro-America" than others. Alaska Gov. Sarah Palin holds a rally Friday in West Chester, Ohio. Alaska Gov. Sarah Palin told a fundraiser in Greensboro, North Carolina, on Thursday night: "We believe that the best of America is in the small towns that we get to visit, and in the wonderful little pockets of what I call the real America, being here with all of you hard-working, very patriotic, very pro-America areas of this great nation," she said.
