Folks, do not be disconcerted. Hillary outspent Trump by tons in 2016. Trump addressed the money disparity at the rally last, essentially saying that his father taught him to be efficient and get a value for the dollar. Extra money need not be spent if it is not needed. Read that as confidence.
Trump just needs to spend enough money in 8 battleground states. I bet Biden will waste money in states he won’t win such as Georgia and Texas.
