I’m not talking about “expanding” power, merely proposing that the USA learn from other systems that have deadlock breaking systems, with limitations to mitigate abuse. I’m not sure taking money out the system will have the same effect, as we’ve seen Republicans gain a lot of political capital by just being obstructive since 2008.
The US political system is completely broken with regards to lobbying and campaign finance. All the money floating around makes it nearly impossible for representatives to work across the aisle, or to ignore the aisle and vote for what their own state wants regardless of party.
