Here is video of Georgia Democrat Rep. David Scott in total meltdown mode after a medical doctor in an open forum asked Scott pointed questions about ObamaCare. The doctor asked Scott if "he was going to be voting" on a health care bill, and Scott said "I don't know." When the doctor persisted, Scott completely lost it and began yelling at the doctor and others in the crowed, accusing them of "hijacking" the meeting.
This video shows much of Scott's meltdown, and also contains an interview with the doctor.
NOTE: During his tirade, Rep. Scott said his meetings were for his constituents. Turns out the doctor IS one of his constituents.
