Name one western country that have elected an anti-China government and say why you think their opinion/action towards China had any influence on them willing the election.

I’m guessing you can’t, because quite frankly, USA is the only western country that have done something meaningful to stand up to China. If Trump gets re-elected then I’ll agree that his anti-China stance and actions won him a significant amount of votes (enough to be deciding factor in him beating Biden), but unless that happens then you’ll have a hard time convincing anyone that a western government rose to power as a result of their anti-China stance.
