I remember an article a while back that compared the amount of money spent by each candidate divided by the number of votes they received in the primaries. Jeb's "cost per vote" was 10x higher almost everyone else's, and about 100x higher than Trump's. That doesn't stop Bush from calling Trump an egomaniac.
And here it is:
