Outside of a new Constitution you're going to continue to be disappointed and frustrated for quite a long time.
We certainly have an ... odd way of running our country, but it's the system we have.
Other Western democracies have a parliamentary system where the leader of the ruling party is also the leader of the country. Additionally, when the "people" lose confidence in the ruling party snap elections can be called and the people can vote to keep the ruling party in power or usher in a new ruling party without having to wait for an arbitrary date to vote like we have in the US.
I share your frustration about our current system. It's a system designed to give overwhelming power to small, largely white states at the expense of large, diverse ones.
Can someone explain how it's fair that the Dakota's, with a total population between the two states of 1,658,026 have four Senators, yet California, with a population of 39,368,078, has two? I can go on and on.
