One of the dumbest things I have ever seen posted on this board.
There are many benefits that term limits serve. I will focus on the most important 2.
1) Term limits would eliminate the biggest problem which Congress has ... the career politician. Term limits would provide more people with real-world experience from all walks of life an opportunity to serve in elected office. More entrepreneurs, teachers, doctors, small business owners, and business execs would be inclined to run, with realistic opportunities of winning. In other words, more talented people. These more talented people would stand a better chance of winning, when they don't have to oppose incumbents with huge war chests accumulated over time. Fewer people running purely for their own self-interest like Joe Biden and Chuck Grassley would be interested, without having as much time to sell influence.
2) Term limits would get corporate PAC money out of politics. 97% of corporate PAC money goes to the incumbents because the lobbyists and special interest groups have already exerted their influence over them. Term limits stop those ties from becoming unconditional, long-term relationships ... which too many Republicans have with the NRA.
