Probably the other way around. Ukrainian ologarchs were buying their way into the Dem party through Biden. They have plenty of other ways to get money and funnel it to Dems without any need for the Dems to take over.
This is a look at Hunter Biden’s business dealing since he graduated from Yale Law School in 1996. He was exploiting every opportunity he could get as the son of a US Senator. I think he intended to exploit Ukraine which was the poorest nation in the region. That’s why daddy arranged things for him.
