( CNN ) -- Huddled around a table for hours , a handful of top journalists at CNN 's political unit has been poring over YouTube videos by the thousands . The Republican hopefuls will face off Wednesday in the CNN/YouTube debate . It 's a laborious process , but it 's necessary to ensure the best questions make the cut for the CNN/YouTube debate between Republican presidential hopefuls in St. Petersburg , Florida , which will take place Wednesday at 8 p.m . ET . `` The questions are funny . Some of them are striking . Some of them are sad . They are incredibly meaningful , '' said Sam Feist , CNN 's political director . `` You watch hundreds of these questions and you really get a sense of what 's on people 's minds . '' The CNN producers have viewed more than 3,500 video submissions from people around the world . They 'll continue sifting through more , through the submission deadline of November 25 , right up to the debate . Only about 40 will pass muster . Watch some of the questions sent in so far » . It 's only the second time such a debate has taken place -- Democratic candidates duked it out in a similar format this past summer . That debate christened YouTube as a venue for prodding politicians and a way to get the public involved . While the GOP debate will also face a YouTube audience , do n't expect to hear the same questions . `` This debate is to let Republican voters pick from among their eight candidates , '' said David Bohrman , Washington bureau chief and senior vice president for CNN . `` We are trying to focus mostly on questions where there are differences among these candidates . '' The White House hopefuls -- accustomed to the political tradition of stump speeches followed by queries from journalists -- have no idea exactly what to expect . `` There is some sense of the unknown and so they 're going to be a little bit out of their normal comfort zone , which is a good thing , '' Bohrman said . Each of the eight GOP hopefuls will answer to real people displayed on a 25-foot screen ( or their animated creations , as witnessed in the Democratic debate ) . The candidates will have to deal with the person asking the question as if that person were in the room . `` They really need to relate to these as people because they are very human . They are somebody somewhere who 's taken the time to submit these questions , '' Bohrman said . And some of those submitters will be in the room -- creators of some of the most compelling questions will be flown to St. Petersburg to watch the debate in person and offer reactions afterward . The user-generated format marks a major step toward involving people in the process of selecting a nominee . It 's also changed the way people view presidential debates . Unless someone happened to be in an Iowa farmhouse or a New Hampshire coffee shop , having an impact on the nominating process was `` impenetrable '' to outsiders Bohrman said , referring to the first two states to hold caucuses or a primary . That 's no longer the case because questions asked during the Democratic CNN/YouTube debate continue to resonate on the campaign trail , according to Feist . `` We 've really begun to find a way for people around the country and even around the world to play a significant role in the process . There 's no going back from this . It may not look like this in 2012 , but I think never again will there be no participation from the public , '' Bohrman said . So will any stars be born during this week 's debate , like when Billiam the Snowman made a guest appearance during the Democratic debate ? Will Jackie Broyles and Dunlap be back with the Red State update ? CNN 's political unit is keeping the questions a secret , but those selecting them say viewers should be prepared for presentations that are funny , questions that are poignant and a format that is unprecedented for the GOP . `` I 'm not going to give you any hints about what sorts of questions we 're going to pick or we 're not going to pick , '' Feist said . `` There are plenty of animated figures out there , there are certainly some funny questions , but more importantly , there are hundreds , if not thousands of really , really good , solid questions from real people on real issues .
