Do you suppose it is their long teniour in the house & senate that has given them too much power of seniority and thus a corrupt bios towards the growth of that power along with the governments that the democrats are always after?
There are several problems.
Some suffer from being in D. C. too long, and becoming convinced that government must fix everything, failing to understand that it screws up more than it fixes.
Then you’ve got your idiots that were messed up when they first came to D. C.
Exposure to the almost exclusive Leftist mindset in D. C., both government wise, media, and private sector, does lead people to begin to think more like a Leftist over time IMO.
That’s my take on it.
