Just curious

If enough corporate sponsors back out, is there a possibility they won't have enough money to hold a convention? Or will the RNC make up the difference, which would force them to use money they would otherwise spend in the election?

I'm not really sure what the corporate money pays for at these conventions. Is it te cost of the basic convention stuff, or just the perks and extras to make it shiny? Will the only effect of all the losses of corporate sponsorship be a bare bones event? Could it cause further damage to the finances of the party?
