Some, beaten beyond the bounds of resilience, never face the race again, never compete for the public vote, effectively electorally put down but not out of their misery. Some, evidently of sterner stuff, wait the required term and put themselves back up for election, ready to either take a beating or dish one out in the public ring.
Don't ever compare this with national politics, where only one can win. This is tag team terror, full-contact monstering of their opponents, dragging them behind their figurative chariots if victorious, being dragged if defeated.
And those who win? They spend the next three years terrified to speak lest they show a weakness, an armour chink ready to be exploited at the next opportunity, the next election.
For parliamentary candidates it's a job interview. For councils and health boards, it's gladiatorial hell. And we love it.
