Citizens United gives the very few the ability to buy that influence and sway an election.
No more than the power of huge government employee unions. From school boards to the Presidency, these unions are among the biggest campaign contributors.
And make no mistake, they look out for the huge "government-industrial complex" to steal a term from Pres. Eisenhower.
Use education as an example. Why rely on every little hick town school board when education can be federalized and put under the budgetary control of just a few hundred; e.g. Senate, House, President?
From department to department, government represents the interests of tens of thousands of entrenched inefficient, well paid bureaucrats. That includes civilians and uniformed military, too.
The objective is for government employment to be as numerous, as well paid, benefitted and pensioned as possible, with no strings like good performance attached.
Until campaign donations are restricted across the board, I will support citizens united, thank you.
