Back during Gulf War I there was a Iraqi Anti-Aircraft Gunner known as "The Red Rope Ranger" Pilots would go on a bomb run into Iraq, and sure enough they'd see this pretty red rope of AAA fire coming up and everyone knew to steer around it. He was what they called a "Level 3" Gunner. They never bombed him or targeted him, even if they had unexpended ordinance. Simply because the pilots knew that if they blew up the Red Rope Ranger, the Iraqi's might replace him with a "Level 8" Gunner. Someone who understood the concept of AAA and could actually hit what he was aiming at.
In fact, Chelsea running is a good idea. She'll run for some safe blue seat in NYC, and become a level 3 congressperson (Hank Johnson, Andre Carson, Shelia Jackson Lee). In other words, like most Democrats, just there to pickup a check and not get caught doing nothing. And it keeps a level 8 Democrat (someone who actually introduces and tries to advance legislation along) out of the House.
