Imagine thinking that even if the Republicans win (which is almost certain, and that's just going by how the party that won the presidency loses the midterms.) that the US would suddenly stop giving shit to Ukraine. Sure, a couple of the more fringe Republican nominees have said to leave Ukraine in the dust entirely, but the most the heads of the Republicans have said is "Stop giving blank checks." which is political code for "We'll say something that makes the Republican voters who want to deal more with domestic issues happy but leave the door open for approving giving Ukraine billions and billions of dollars every month."
Calling it now, even if the Rs sweep the midterms, we might see a 20-30% reduction in funds given every month to Ukraine tops, and realistically won't see a notable dip at all.
