> Are you saying the least competent candidate is always the one who gets elected? Or just that only incompetent people become politicians?

The candidate that is most capable of being elected is the one that either:

- Can garner the most votes

- Can prevent other candidates from getting votes

Nowhere in the above is technical competency a requirement to be elected. It may help, but its far down the list of "electable attributes".

The skills to get elected rely on being about to lie to people and lie to yourself as much as possible and be a narcissist at the same time, so all of these factors make it VERY unlikely that they correlate with actual competency.
