(CNN) - The Republican National Committee is stepping up its efforts against Barack Obama, launching a new Web site Friday that solicits voters to question the Illinois senator on issues "he has failed to address or refused to answer."
The site is encouraging both text and video submissions via YouTube. It also features a Web video suggesting certain questions to ask, including, "Why, as an Illinois state Senator, did he vote 'present' over 130 times instead of 'yes' or 'no' on difficult issues like abortion, crime, and guns?" and "Why did he tell donors in San Francisco that the economy has driven small town voters to 'cling' to guns and religion?"
