There is this story I read from many years ago about time travel stuck in my brain.   

The story went something like this:

Before the guy travelled back in time, in passing he heard the news on the radio the results of the election.   The good sensible wise leader had been appointed leader.  He had beaten the dictatorial candidate who would have been damaging for the country.   

The guy breathed a sign of relief and continued on.  

Soon afterwards the guy travelled back in time.  

I don’t remember too much of the story, but one thing I remember was the guy was walking along a track in a forest.   He was instructed to never step off the path, not to step on the forest floor, or that could alter the future.   

But did he listen?  No.   He stumbled and stepped on something maybe a butterfly or something, maybe it was just breaking off a small branch—just a small seemingly insignificant change that didn’t really amount too much.  

The story continued and eventually he returned to his own time, just before he had left.

Then he listened on the radio the news report, but there was a significant change: the dictatorial candidate that was bad for the country had come to power and would rule the land.
