90% of Bernie's wealth is campaign funds. Presidential candidate is what he does for a living.

I gotta be honest, if I did not have to listen to her political rhetoric I would give Kamala a go between the sheets. She looks to me like she would give maximum effort in that arena.... Just sayin'

She is at least 5 times better looking than Horsey Tooth AOC.....

Bernie starts a media buying company...runs it out of his living room with his wife as the boss...10% of all of those millions in donations that go to ad buys go to the media buyer. Bernie and his old lady have been scamming for many moons.

From what I've read the money can't just stay with the candidate once his/her election bid fails, unless said candidate plans to run again for office (not sure how that is handled officially). Otherwise the money is either donated to the party or another candidate, etc. Pretty sure there are built in loopholes throughout this process though.
