Because our government is run by human beings it is not, and never will be, perfect. There will always be corruption and fraud. My concern is how can we reduce it as much as possible? This is being asked not to point fingers or blame either party but to try find a bipartisan solution to a bipartisan problem.
Churn. We need to remove the current Republican and Democratic leadership and replace them with better leaders. Let's start by removing all the Republicans and see how that works. There's 90% of the problem. I mean that sincerely. Trump is deeply, deeply flawed in every possible respect, and he has surrounded himself with the worst swamp creatures the country has ever seen. The Republican House and Senate are just as bad (and where a lot of Trump's swamp creatures came from). Hard to place the blame on Democrats as they have been out of power, so it will be harder to determine who has to go.
One huge obstacle to reform is the corrupt Supreme Court majority. The number of really, really bad and purely partisan decisions is growing rapidly (including yesterday). As examples, Rucho v. Common Cause
, Citizens United, Shelby County v. Holder, Bush v. Gore. One the current court, "Whatever idiosyncratic legal views Gorsuch and Kavanaugh might otherwise hold, Trump’s Supreme Court nominees both appear firmly committed to one of the Roberts Court’s great projects: maximizing conservative structural advantages in the American political system." The Supreme Court Steps to the Right
(New Republic). At least 2 members are just unsuited for the post - Thomas, and Alito (and probably Gorsuch). But, they can't be replaced until Trump and Pence are gone and a Democrat is in office, so... there is that.
There's no doubt we are in for a really, really rough patch over the next decade. Replacement will take time. The biggest suggestion: Vote blue, no matter who. The rot goes all the way to the States. The biggest flaw with the OP is the false equivalence concept that "it is bipartisan." While nominally
true, the bulk
of the problem is on one side of the aisle. As long as money is the driving force, though, it will continue to be the primary issue.
