There has to be some lag, and it is more about who controls Congress.

For example, the housing crisis and bubble were largely driven by legislation passed years earlier, including the 1999 repeal of Glass Steagall under Clinton. That was passed by a Republican controlled Congress, and the crisis eventually exploded under Bush. So I do not think either Clinton or Bush can be directly blamed for the housing crash. It is the repeal of the glass steagall act.

And was the dot com bubble crash in early 2000s caused by Clinton or by Bush? Or some legalization passed a long time ago? Or it just a business cycle?

More broadly, I would argue that presidents, and even legislators, have limited control over the actual health of the economy. Are we going to say Trump is responsible for the AI boom? And if this AI boom collapses into a massive bubble burst under the next administration, will that president be blamed instead?
