We need election reform but I'm against term or age limits.
Encourage younger voters and politicians. Remove the current age limits as we're obviously not using them. Make state positions something a young person can live on, right now they have to keep their job and hope the boss is ok with them campaigning for months to just do a short legislative session.
Change campaign laws, Citizens United has shoved so much money into the system, we campaign for months, reducing the effectiveness of elected incumbents and winnowing out the candidates who can't fund raise the entire time.
Uncap the House, they passed legislation in the 1920's to limit their number to 435. Meanwhile they are now granted staff based on the population of their state. We now have more legislative staff than we would have Representatives if we kept to the original 30,000:1 that George Washington did the first presidential veto to keep.
