And my point still stands. You will have constantly 4 representatives who will have their voice mattering much less than the 5 others----> inactivity
Not saying your point lacks merit, but would it be valid inverted? As in, if 4 Representatives being less powerful than others leads to less activity, would 5 Representatives being more powerful than others lead to more activity?
I don't think so. After all, there is a limit to how active one person can be - no matter how little social life you have, real life will eventually get in the way. I can also attest, having spent three terms in the Senate and three in the Mideast Assembly, that legislators do not become more active when their colleagues go MIA.
I'm okay with a partisan House leadership, but the minority party should not be sidelined in the process (fortunately, it doesn't seem like that's what you're proposing). As Blair pointed out, that arrangement pretty much killed South America. We should order the House on the model of the real life US House of Representatives: give the Speakership to the majority party, but allow everyone to propose bills and try to cobble together a coalition to pass their ideas.
