> is 1 really true? we have elections every 2 years for it. how many periods of time have we had no change in control of the senate or the house for 4 2 straight elections? what about fo 4 straight? vs how many times we've had dual term presidents? (serious, don't know the answer to that question, though i could probably look it up)

You can take a look here: https://en.wikipedia.org/wiki/Party_divisions_of_United_Stat.... You'll notice that the individual chambers of congress change hands less often than the presidency.

Additionally, Congress has a high incumbency rate. Even in huge swing years like 2018, the makeup of Congress remains largely the same.
