So what you're saying is that Trump essentially won twice by default lol?
Pretty much lol,
Nah the professors take was pretty much same as someone else mentionned in previous page. In other western countries, prime ministers (or presidents) get elected as females easier because the focus is on the party first and foremost. And only second it is the leader.
Parliamentary coalition government's Party leaders are generally just another employee who work their way up to the big seat or theirs rotation chair of leadership until someone eventually gets the main seat in any given election that party wins. Its why boring hacks like Teresa May get their turns lol Just another high profile employee. Didn't go through the hunger games to get the job.
While the US president the main focus is not so much on the party itself but fully and utterly on the charismatic individual, the prestige of the presidency, it becomes hyper focused on that as an icon (like Kings were in the past), like its almost a cult of worship almost at its peak. Way before a trump, JFK and Reagan became larger then life superstars. Or how much Obama & Clinton being "cool" or smooth became a thing. After success its very much becomes a star power thing. And only secondary then it's the party and politics.
It's an aspect it's way easier for male leaders to stand out in then female ones. Especially when you compared to an entire catalogue of past figureheads that were all males in the fairly young nations history.
Rare exception unless you are Finlands former prime minister Sanna Marin. She wasn't an anonymous leader pushed up to the coalition seat. She was pretty much a rockstar that looked like a model. Stood out with charisma and became more of a talk then her highest seat itself lol But in Finland it's not as cool to stand out too much so eventually it became to her detriment.
