As you can see, double-digit change has happened in the House in every election since 2006, with a 22 percent shakeup in 2010, when the Tea Party revolt swept in 94 new members of the House - with 78 people arriving two years later in 2012.
But the numbers are even greater than what you see in the above graphic, because those changes don't take into account all of the churn which happens outside of a regular election, when lawmakers leave their seats for a variety of reasons - death, personal/family, ethical matters, or they just decide to resign early.
For example, in the current Congress, one House member died, and 15 others resigned on their own; in the Senate, one Senator died, and two others resigned their seats.
That type of turnover is often overlooked, but it adds up.
If you take Massie's six year observation and look at the new Senate in January, at a minimum there will be at least 41 Senators who have only been in the Senate for 6 years or less - and that's if no incumbents are defeated on Tuesday.
If you go out to eight years of service, then more than half of the Senators will have been around for 8 years or less, with close to two-thirds serving 10 years or less.
I know people will immediately write me to say, "Yeah, but so-and-so has been around forever!" - and yes, there are examples of lawmakers in both the House and Senate who have been there for a long time.
But turnover continues at a decent pace in Congress - if you actually dig into the numbers.
