Alternative to Term Limits

I don't think there's a good chance term limits will pass based on some reporting I've come across.

I think there are good arguments for and against term limits.

Proposed compromise:

Term limits for the House of Representatives. There are a bunch of these people: 435 to be exact. There's less of a reason to have professional politicians in the House. I've seen proposals for 3, 2-year terms. I think this is a little short. I'd advocate 5, 2-year terms. A decade is enough to gain experience of being a House Member while also being able to use some of that experience.

Here's the unique idea: no specified term limits for Senators. Actually, no defined terms at all. INSTEAD, allow State legislatures to call for a special election. As most of you know, the States selected Senators before the 17th Amendment changed it to a popular vote. This idea is a compromise between repealing the 17th Amendment and instituting term limits. Current Senators stay in place. However, a state government can pass a bill to hold a new election for a specific Senate seat. It's basically a recall on an elected official. The thing is that the person being challenged can still keep their seat by winning the challenge that is determined by a popular election within that state. So, a popular vote still elects US Senators, but the state government decides if and when to hold these elections. Thus, some Senators would rarely get challenged and, thus, rarely have to worry about running elections. These Senators can focus entirely on their job and hold senior positions within the Senate. Some Senate positions would be constantly be challenged. These positions would result in new blood and tip the balance of power in the Senate.

Issues? Any thing bad about the proposal? Good?
