You seem to be implying that a root cause of the accident was the political spreading around of construction.

Rockets are incredibly complex machines, you could use this sort of post hoc reasoning to find cause and blame for any anomaly by saying such a part could have been done differently. You couldn't ever use this reasoning to make design decisions that prevented accidents.

What it really comes down to is that the Challenger exploded due to man's folly in exploring outer space. /s
