What would be the solution? More frequent elections are welcome to me, every 2 years or I'll take 3. That should hopefully lower the delaying strategy and easily sniff bribes since they don't have much time.
The same could be done for basically all political offices. Essentially, any person with any political power would need to be able to justify them holding that power for every second they hold it, and the moment they can't, or the people decide they can't, that office should be abolished.
Many early human societies organized this way.
