Enact performance based pay for elected officials. Include provision to reduce pay by 25% when running a deficit.

Performance based pay is common in industry to ensure people's personal motivations are aligned with that of the business. By adopting this practice for elected officials, they would have a personal financial motivation to behave in a way that aligns with high level objectives, which, on their own, enjoy a high levels of bi partisan support.
If 50% of their pay was based on their performance of key metrics they would be motivated to drive the country to succeed. These metrics can be staggered (i.e. 25% devoted to balancing budget, but realize 15% if deficit is less than 3% of GDP.), and they should be objective measures of common good. (GDP growth, financial stability (i.e no continuing resolutions), unemployment rate).
Otherwise they are only motivated to align with special interest.
