Are political journalists always wrong?

What I do know is that Senior Political Correspondents collectively shat their pants with excitement at being able to breathlessly report any half-baked gossip which would drive clicks. In an article called "Is The Economist always wrong?" I'd like someone to run the same process on the political rumours reported by the mainstream press. Perhaps journalists are hanging around in bars and listening to SpAds boast about what the boss has just said. It would be fascinating to see if any political journalist has a better than 50% ratio of hits to misses.
