Every politician says they are in it til the end. But numbers, especially those following the $ sign, can be a very inconvenient factor. In the long run there comes a time when you need to man up and accept defeat. I have always marveled at the arrogance of candidates cluttering a debate stage, with each speaking of “when I am President...”
And all the while I am thinking, “all but one of you are going to have to learn to live with disappointment.”
I wondered about this when Weiner stayed in his race till the end even knowing at the outset that he had NO chance. It turns out that if a candidate stays in the race till the end, (s)he gets to keep the campaign donations.
