My generation in the UK grew up with America being this shiny, free, wonderful, aspirational land over the sea, the land of Baywatch and Miami Vice and Disneyland and CocaCola all the other things. It really did appear to be the mythical shining light on the hill. I love visiting the US and have spent over a year there now, on and off. It is a varied land of contradictions and of very different values and lifestyles, a land of opulence, but also of left behind little places. But the politics ... it seems to have become pathological, and the population increasingly cynical about politicians, about the media and sources of information, to the extent that most trust seems gone and consensus reality seems to be frequently called into question (I'm not claiming this is unreasonable! Just observing).
These tropes are definitely present in the two countries I've called home, but to a much lesser extent, the poison doesn't seem to have permeated quite so far.
You do see stuff get thrown around on social media like "Make sure to take a pen to the voting booth so that they can't change your vote!" but it's fringe whackos. Even if the politicians themselves are disliked, the mechanics of democracy are usually pretty well trusted. IIRC in the last general election here one of the tiny right-wing parties tried some voter-fraud type rabble-rousing ahead of the poll, but they were largely ignored and pretty quickly contradicted by the Australian Election Commission.

Finchem promotes the big lie and says he will use his prospective position (which AFAICT includes responsibility for administering the election) to "make sure that Arizona is the Red State it REALLY is!" - https://twitter.com/derekwillis/status/1403143345132781569
It's true, that last one is perhaps not as cut-and-dried as it could be, there's some wiggle room in there, but to me the intention looks clear. It's fecking crazy to me that a partisan, elected official has anything to do with running the elections in the first place... but there we are.
I'm sure you can find more stuff like this if you look. Of course I'm sure that there are all sorts of excuses and justifications out there for why this is all totally reasonable, or why the 'other side' are just as bad. It's not clear to me they are though, at least, not when it comes to trying to actually undermine democracy itself.
Multi-pronged attacks which try to ensure only 'your' people get to participate.
As an Australian resident and a British citizen, it seems outrageous to me - I've never had to take more than about fifteen minutes out of my day to vote in the UK, and in Australia voting is fast, mandatory and always run on a weekend so that most people can get to it. They even usually have a charity barbecue outside the polling place!
Other, indirect attacks on the system include Trump's big lie, the stated intention of the republican candidate for the secretary of state of Arizona to return the state to republican control because he thinks it's what the people really want regardless of the outcome of the actual vote (because clearly the vote is rigged!), the various "alternative electors" that republicans attempted to send to congress during the aftermath of the last presidential election etc etc. The US right is currently mounting an attack on US democracy itself in various ways, to try and work around the system and usurp democratic mandate.
