Presently I am reading "A Question of Character: A Life of JFK" by Thomas C. Reeves.
In 1960, everybody knew a US invasion of Cuba was going to happen: newspapers, activists, DOD, Congress, and most importantly, Fidel Castro.
Under "Ike," Cuban ex-patriates were being trained by CIA in Guatemala ("Brigade 2506") and the "secret" was a sieve.
The only unknown was when the attack would take place and the precise location in Cuba.
The US was to provide no uniformed personnel or equipment, so CIA and USAF planes were disguised and the operation would therefore be a purely Cuban "counter-revolution."
The Bay of Pigs was unwisely chosen and Fidel's tremendous, well-motivated, and well-equipped army was ready for Brigade 2506.
The always victorious JFK had to suffer his first public black eye as POTUS and he furiously wanted to dismantle CIA, "casting it into the four winds."

-You think the voters want those donors sending bribe money to their candidate?
yes. People have a way of rationalizing it. They (most of them) can switch sides anytime and folks will be fine with it.
But it's also about getting more out of the current large contributors. Their pockets are deep...they just need a better reason.
-It's not about big donors if you want to get people motivated.
Sure it is....you use that money to "motivate" the masses.
