Okay, finally met the other continent. Despite founding the 5 first religions, they still managed to somehow get together in a huge religious lovefest over there. By the time I found them, they all had Lit, Feudalism, Construction and Theo on me. I had Compass, Optics, Philo and CS on them. Almost completed Astro by then also. My plan earlier was to get Lit, Construction and Theo in a peace deal from Ramesses, but now I killed him completely instead. Anyway, their tech pace is pretty fast, might not be able to Lib Radio. Maybe settle for Physics instead, or Electricity, in case I need Physics GS for Golden Age.
Now I have to figure out how to get the votes. They all really love each other. Except the lone backwards Buddhist hate target, Isabella. I suppose I could get them all into a mutual war with Isabella, but that would also increase their love for each other, so maybe not worth it. Their mutual love should come to an end once they get access to Free Religion, I hope. I can use spies to switch them into Free Religion if they don't do it on their own. I currently have 30% of world population, should go up as my fresh conquered cities get a chance to grow.
I'm also considering sending in my army to kill Isabella, then liberate the cities to whoever they belong to, looks like 2-3 cities for Asoka, 2 for Washington and 2 for Roosevelt. Not entirely sure as I haven't located all capitals yet. Nor do I have open borders with Isabella. However, I'm CRE, meaning I will be generating culture as soon as cities come out of resistance. How does this affect my possibilities of liberating cities? I notice I cannot liberate any of the cities I conquered from Ramesses to Freddy or Peter, despite their capitals being closer to the cities in question. Is there a limit on how much culture I can have in the city? Looks like >50%...
Mansa is in the north. If I can find some free arctic lands to the north of him, I could send in a couple of settlers to either liberate cities to him, or make him a land target for peace vassaling. Maybe I could make some more peace vassals also, if I find the spots to put down my settlers. Freddy (10 cities) is already willing to peace vassal to me. Not sure if it's worth it though, I should easily get him to Friendly anyway, and if the other civs don't end up liking him, he might prevent me from getting some votes, right?
As long as they don't make Peter (on my continent) their worst enemy, I can also build UN and gift the city to him to make him my opponent, right? Hammurabi is the largest civ on the other continent. He likes Bureaucracy, I like Bureaucracy, we are a match made in heaven.

His votes should be a lock as long as he's not running against me.
So, what am I forgetting? I'm currently gifting them all 4-5 resources each for "appreciate the years blablabla" bonus. I'll have to give in to all demands and requests, which sucks if they want something that gets them towards lib... And they'll happily trade around what they ask for as well. What else should I be doing?
Since I met them so late, I might not get much of "you shared your technological discoveries with us" bonus. But for that it doesn't matter if I give them the tech right before they finish researching it themselves, right? With my empire originally set up for espionage, I can easily keep track of what everyone is researching.
Here is the bunch I'm dealing with (Freddy and Peter on my continent):
I'll have to choose who to share favorite civs with. Roosevelt is larger than Mansa, might have to go Merc. Free Religion is a given, as is Bureau, if I can make sure Hammurabi isn't my opponent. Then either Rep or US. Might need US to rush buy UN if I can't get my hands on a GE.
