Reform the E.C?

Automaticallly and almost sarcastically I say "Why not? We're trying to reform everything else."
then I get to thinking, what exactly does this entail. So in the little quiz I am currently taking I have gone No, Yes....but have looked at both arguements. The arguements against it make very little sense and have little strenght in them aside from it would call our Constitution into question which is very disquieting to some people. One arguement I find weak is: if the E.C is changed why not change the senate and house of reps? Well if it ain't broke don't fix it right? It would seem to me that the senate and house of reps election bases are working fine. But the E.C. is broke or has some bolt screwed loose so why not "fix" it? The way it works now the "little guy" has more say than the big one. Ok fine...but then doesn't that mean that the president will most likely be a propoenent of that regions ideas? (this is opposite an arguement I read) On the other hand the E.C. has a way of getting small groups interests into the two party system by trying to address thier needs. Remember there are different parties other than the Democrats and Republicans. But I wonder what would happen if those other parties were given a fighting chance...I imagine there would be more differing ideas in the government which could cause one of 2 things: 1. the differing opinions would fight against each other so terribly that nothing would get done or 2. the different opinions would find the best in each others ideas and COMPROMISE like the founding father's did and better things would get done.
I ended up saying yes because quite honestly the arguments against Yes barely made sense to me and appeared weak. So maybe don't chuck everything out the window but tweak it so that it works a little better.
