The career path for a Democrat is

1. Get into national politics
2. Don’t offend the corpos so you can build connections with them for Step 4
3. Don’t rock the boat so you keep your political connections for Step 4
4. When its time to retire, join a lobbying firm and use your political and corporate connections for a nice cushy paycheck.

Which is why they hate any democrat that rocks the boat: they’re endangering their retirement.
