Kbin/Mbin (and possibly others?) definitely have the edge here since those platforms make votes public (only admins can see them on Lemmy). So, if you want to confirm what I'm saying here, go view some of these posts from Kbin/Mbin.
Every time one of the "usual suspects" says stuff like this in the comments, there will later be posts detailing how Biden is doing (or at least earnestly trying to do) exactly the things they're saying he needs to be doing (oR ElSe i WiLl noT voTE anD NEithER ShoULD yoU!!!11!!). 100% of the time, those posts are downvoted by these same "usual suspect" accounts.
What gives? They have very strong opinions about how he should run his administration, so you'd think they'd appreciate him doing what they've been so helpfully suggesting. Unless....it was never about the issues at all.
That thin veneer of concern they're hiding behind is not as thick as they think it is and is quite easy to see through. Now you know where to look.
Edit: Please don't name and shame any specific users. That may violate the community or LW rules. We all know who most of the "usual suspects" are.
There is no such convention.
Sometimes they can make a deal with minor parties to ensure they have confidence and can pass supply bills (a confidence-and-supply agreement, like Trudeau and Jagmeet have now), but they usually don’t. And that's why minority governments usually don't last long in Canada. (Typically no longer than two years.)
Stephen Harper's minority government didn't have a confidence-and-supply deal. They stayed in power because the Liberals would abstain on confidence motions (until they didn't).
