Let's try an analogy.
We have a lottery for $1 million. The odds of winning a lottery are 1 in 1,308,120,372,038,273,128,102
A realist says there is very little chance and doesn't buy a ticket. Right off, we can tell off that his odds of winning are exactly 0%.
Now, we have someone who doesn't have much confidence that he'll win the lottery, but buys one ticket. All of sudden, his odds skyrocket from zero to a small chance. The gap between zero chance and small chance is much more larger than the gap between small and better chance.
Now, suppose we have another guy who decide that he can win lottery! He hocks everything he has, and makes a big loan from the bank to scourge up $100,000 and squander it all on lottery tickets. Now, he has much better chance than the first guy who bought one ticket, but the payoff is much more bigger. He loses, and thus is penniless, bankrupt and doomed to wander the streets in his despair for his folly.
Now, suppose someone read the lottery rulebook and found out that lottery permitted a pool, so a group of people got together and buy several tickets. Now they have much more better chance than that one guy who bought one tickets, and they don't risk as much as that guy who betted everything.
Now here's how this works.
The first guy is whoever never was a Presidential Candidate.
The second guy is any third tier candidate.
The third guy is Ross Perot.
The group who worked together are Paulites working to be delegates to various conventions.
In end, the group has the best outcome, even if they lose, because they now have invested into something: the GOP party.
