Balanced partnership in the elections of the congress is one of the characteristics that has changed in the last decade. The congressional election is another parameter that has changed in the last decade.
Yes it has. Every two years there will be some change. All members of the House of Representatives are up for election. Every two years one third of the Senators are up for election. Senators are elected for a six year term. That is why the Democrats still control the Senate today. Only one third of them were up for election last time.

As of 2021, 82% of members of the 113th Congress identified as white, 9% as black, 3% as Hispanic, 2% as Asian, and 1% as Native American. These figures may have changed over time as new elections have taken place.

I strongly suspect that all members of Congress, Republican and Democrat, who are over 65 are enrolled in Medicare - their health insurance plan probably requires it.
A rate of over 90 suggests a high level of agreement or consensus among members of both houses of Congress. It could mean that members from different parties are often voting together or that there are few major disagreements on legislation. Such a high rate of agreement is relatively uncommon in a politically polarized environment like the US Congress.
The number was set in 1789, but has changed over the years.
Yes. All you need is a battery eliminator with the right characteristics.
Recess. There are two types of recess. One is used routinely to recess for a period of time, usually over the summer or winter break. Congress then reconvenes once that break is over. Congress can also be recalled or reconvened during times of emergency. A Sine Die Recess occurs every two years when the congress has ended. That congress is recessed permanently and will not reconvene until the new members of congress are sworn in. After a Congress recesses Sine Die, all pending legislation on the calendar is disposed of and the calendar is cleared. Any legislation that has not been considered by that time, must begin the process all over again.
Individual members of Congress certainly are, but the structure of the legislative branch is such that it's not really possible for it to favor one state over another. Since members of congress are elected by their congressional districts, and individual senators are elected by the citizens of their state, it's natural that these members would favor their own constituencies over others. The states are given representation proportionate to their populations in the Congress, but each state has two representatives in the Senate regardless of population -- this is intended to make sure there's enough representation for citizens of a large state while citizens of small states aren't drowned out.
In the US Federal government there are two parts of the congress. In the House of Representatives, the Speaker of the House presides. The party with the most members choses the Speaker. In the US Senate, this law making body is presided over by the Vice President.
No. The Presidential has little power over Congress. The most he can do is to veto legislation, but they can override his veto if they can get 2/3 of their members to agree to do so.
