Collusion is an agreement, usually secretive, which occurs between two or more persons to limit open competition by deceiving, misleading, or defrauding others of their legal rights, or to obtain an objective forbidden by law typically by defrauding or gaining an unfair advantage.
For the collusion going on in the Senate the two or more persons are almost all Democratic and Republican senators and the open competition they are limiting is challenges to their incumbent seats. Its simple any incumbent has a huge and growing advantage over all challengers coming from corporate donations. But passing regulation of any sort potentially flips this advantage to their competitors. So the senate has reached illegal agreements to pass as little legislation as possible.
In order to reach this agreement the senate had to circumvent the constitution which has language designed to prevent dead locking our government
The Vice President of the United States shall be President of the Senate, but shall have no vote, unless they be equally divided.
Therefore this collusion also requires the vice president to illegally go along
The president of the Senate, the vice president himself, could issue an opinion from the chair that the filibuster is unconstitutional.
You also need collusion with the POTUS in order for congress to unconstitutionally give up their duty to prevent endless war
To raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years
and unconstitionally allow the federal reserve, in its current form, to exist
No Money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law; and a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time.
(S. 604 "Audit the Fed Alamo" not doing so well.)
And you need the Supreme Court to overlook and encourage the whole system. Plus throwing in a lot of talk about bi-partisanship doesn't hurt - in this case bi-partisanship just means we all have a common interest in preventing equal funding of our political challengers.
What you can do.
I think start using the words unconstitutional and collusion whenever you can. Towards that endread the constitution. It's short and, though dated in some places (to busy battling kings to worry about CEOs), these people were really on the right track
No Title of Nobility shall be granted by the United States: And no Person holding any Office of Profit or Trust under them, shall, without the Consent of the Congress, accept of any present, Emolument, Office, or Title, of any kind whatever, from any King, Prince or foreign State.
