When I assert that anyone who would be a good legislator must have some basic life qualifications I base that assertion on the example outlined in the Constitution where requirements are set for members of the House to be at least 25 years old and members of the Senate to be at least 30 years old. Basic age requirements such as these may be among the few life requirements that are truly objective and quantifiable but I believe they are indicative of a largerĀ (although still limited) set of subjective requirements that must be met by a good legislator. The age requirements set forth are appropriately different for different offices. The purpose of the age requirements is the same – it is intended to promote a level of maturity and life experience commensurate with the duties of the office.
Another subjective requirement of a good legislator include the ability to connect with the people that they would be representing so that they can understand their constituents and relate to them. Obviously they cannot expect to experience everything of concern to their constituents, but the ability to listen and empathize with those they represent. Due to variety among the constituents empathy will not always mean agreement but so long as the legislator feels that they are above the constituents rather than among them they will be unable to accurately and dependably represent their perspective within the legislative body.
The last subjective requirement that I would include is a degree of stability in the life of the legislator. While anyone can have their life disrupted unexpectedly it is unwise to choose a legislator whose life is currently riddled with disruptions. In a stable society the effects of legislation are often long lasting and thus should be protected as much as possible from avarice and caprice. Witness the situation in Massachusetts where the democratic legislature made a law when they had a republican governor that the governor could not name a replacement in the event of vacancy in the seat of their senators. Now a few short years later they have a democratic governor and an actual vacancy – so they change the law rather than wait to fill the seat after a special election as they had prescribed before. It is important that legislators have lives that are stable to give them the best chance at creating laws which will also be stable. A legislator who has a life currently marked by stability will be more likely to plan for the future for himself and for those that he represents.
