Why we should all be terrified of Donald Trump winning in November.
Shouldn't it be "of Donald Trump's" in this example? —since this seems to be a gerund rather than a participle.
"Of Donald Trump's winning" to me is the same as "of Donald Trump's win", while "Of Donald Trump winning" is similar to "Why we should be terrified that Donald Trump wins in November."
However it doesn't look like one would ever use that construction here so maybe that's the reason the objective was used? One of my online dictionaries says "rely on somebody doing something" were correct. So this would be another example of the objective + gerund construction although I have been told gerunds are never preceded by objective cases.
