List of Presidential elections in my lifetime Democrats have won: 1996, 2000, 2008, 2012, 2016.
List of Presidential elections in my lifetime Republicans have won: 2004.
Despite this fact that Clinton won by over 2 million votes last year, and that the Democratic party consistently wins more votes than the Republicans in nationwide elections, the only way to give the Democrats a real chance of this being reflected in the house using our current election method is to gerrymander in their favor. This is because of how Americans are split geographically.
It is impossible to make First Past the Post Single Member District (FPTP SMD) a truly proportional system no matter how you gerrymander. You will always end up with wasted votes, particularly in urban cores where you can get candidates winning by over 80% of the vote, and places where parties simply decide to not run a candidate due to there being no chance of winning.
What this does is it denies Americans a real choice in who elects us. Every vote past the 50% mark in an election is a wasted vote, because the election outcome would not have changed if that person had changed their vote or abstained. The FPTP SMD system inevitably increases the number of wasted votes in the country. Five Thirty Eight has shown we will never be able to make a system which accurately represents the desires of America with this system in their current project analyzing gerrymandering. It is not possible.
There are several solutions of course, mixed-member proportional, party-list, and single transferable vote are the most commonly used in the world today which work better to accurately represent the will of the people.
Party list is used in a large number of countries. Instead of voting for candidates directly, voters vote for the party they like the most, usually with only one vote. There are multiple ways of apportioning seats. There are many countries which use this system and end up with multiple competing parties, none of which has too much power, keeping them all in check and relatively responsive to the people. As long as a party is allowed to get into power if they win one seat this system can function extremely well, which is seen in Argentina, Austria, Bulgaria, Croatia, and many more. This also minimizes wasted votes. In a 435 seat legislature (to pick a semi-random number) under party list the number of wasted votes in this system is limited to 0.23% of total votes passed.
Mixed-Member Proportional is used in Germany, Bolivia, Lesotho, and New Zealand. This keeps the FPTP SMD at the local level, but then has a party list on top of that. There is a fixed number of districts and representatives coming from that level, on top of which you add members from the party list system as described above. Usually this is done until the percentage of seats each party has is as close as possible to the percentage they received on the party list which usually uses FPTP. You still usually end up with two main parties and smaller parties needed to form a coalition in the long run if you have a high threshold like Germany has which prevents smaller parties from gaining influence. That is one reform I believe Germany needs to do in order to make their system work better. You can still end up with large numbers of wasted votes at the district level, but having a flexible size of your legislature can fix this problem. The percent of votes which can be wasted is again limited to 1 divided by the number of total seats which are done by party list. The limit of wasted first mark votes is still 50% of votes passed in every district, assuming the district level uses FPTP.
The third option is used in Australia and Ireland, and that is the Single Transferable Vote. Candidates run in districts, and there are multiple winners for each district. As a ranked voting system, the candidate with the lowest vote count is eliminated and their votes are redistributed until the number of candidates who have reached the threshold required to be elected (usually number of votes / (number of seats + 1) + 1) is equal to the number of seats available. This is the Droop Quota and it gives the right answer all of the time for how many votes are required to be elected. Candidates represent their area and every district is competitive. You could theoretically use STV instead of FPTP in an MMP system, but this is unlikely.
With STV the biggest question is how you are going to redistrict, and there are several good ways to do this, you can focus on single split line or making districts which are as round as possible, you can try to follow existing boundaries. But the biggest point of all is that as long as you do not specifically gerrymander to favor one party or another your number of wasted votes is very low. You strike a balance between local representatives, so people who are out of the political mainstream can get elected which is one potential disadvantage to a party list system, and voters can vote for whoever they want for their first choice without their vote being wasted if their candidate is less popular the other candidates. In a 5 person race the number of votes wasted is limited to less than 20% of total ballots cast.
A fair election in the United States would use one of these three systems. I personally favor STV because I don't like giving political parties power (which I know is a very American sentiment) but I also like the extremely small number of wasted votes party list provides.
We need election reform as soon as possible. We have three main options which are tried and true across the world. Now we need to implement one of them. It doesn't matter what issue you care about, health care, education, infrastructure, foreign relations, environment, tax policy, economic regulation, scientific investment, if you don't have a good government you will not be able to reliably get good policy on any other issue and corruption will increase.
Appendix A:
Maine has already voted to allow ranked voting for state elections, on Wikipedia there is a phrase which I believe needs translating to English:
Bullshit: "On October 23, 2017, the Legislature voted to delay implementation of the RCV law for all races until 2021, to allow for time to pass a state constitutional amendment to allow it.
English: "On October 23, 2017, the Legislature voted to delay implementation of the RCV law for all races until 2021, to allow one more reelection before all the motherfuckers are kicked out of office because if they really wanted it to happen they already would have passed a constitutional amendment."

FPTP: First Past the Post, the system used by the United States for Congressional Elections
MMD: Multi-member district
MMP: Mixed-Member Proportional
SMD: Single-member district

Trifecta: when one party has control of the Executive and Legislative branches of a bicameral Presidential system (eg. The United States except Nebraska)
Appendix C, news update:
Putin is the first President in American history to have a government shutdown when his party has a trifecta. (Oh, it's Trump? Silly me, a small typo, I got into the habit of substituting the Premier of the USSR with their satellite states when studying the Cold War. Wait, Russi is no longer the USSR? I couldn't tell the difference.)
