Who said the federal government must create term limits for Congress? It could be a constitutional amendment or simply something decided on a state by state basis. The president represents the entire country. I'm not sure where this idea that we have a representative government with Congress, but not the president, comes from. Yes, it's a different kind of representation, but so is a Congressperson and a governor, and many states have gubernatorial term limits. I'm not sure how the Congress we have, which clearly is seen as representing lobbyists, legislative staff, and bureaucrats by many people, would be worse off in that regard with term limits. It seems to me it would be harder for the outside influences to work on the representatives because they would have less time to do so, and because the representatives would have fewer elections to worry about. Experience is certainly an issue, but term limits do not have to be for a short period. There's no reason the term limit couldn't be 3 or 4 terms. Having the same Congressperson in office for 30+ years, often running unopposed, doesn't seem particularly representative to me. Term limits are not some sort of magic wand to fix the problems in government, but the current system doesn't seem to be working all that well. Term limits have worked well enough for other offices, I don't think it would cause insurmountable problems to have them for Congress.
