“This is a huge decision, makes it infinitely harder for him to raise money,” conceded a person close to the Trump operation. “Facebook was the main way he raised money. He’s now going to have to spend far more in the future to find other ways to raise money … It was the main way he found donors.”... “It makes it more difficult for him and it gives everyone from Tim Scott to Nikki Haley to Mike Pompeo to Ted Cruz the ability to go out and begin to win over the Trump donors and voters that exist in a vacuum that Trump is not filling,” said one top GOP operative. Already, GOP groups like the National Republican Senatorial Committee are running Facebook ads keying off Trump’s battle with “Big Tech” — a sign the party sees the flap as a strong opportunity to engage supporters and that Trump’s visage remains one of the best ways to draw in donors on Facebook. But Trump himself can’t tap that universe, at least for the time being.
