United States Politics: ∆τ_i*ε*φ*m_i<0 where ε=4 and φ=0.25

[Nintex]

There is only one candidate who would never drop out like a loser and keeps up with the grind no matter what happens or leaks   

Other politicians really underestimate the effect it has on morale for their supporters.
Why would you stand behind your candidate if you know that the slightest inconvenience makes them drop out of the race. 
Giving up only signals a lack of confidence, you should always stay in the race until the very end.
