Dems are polling higher in Kiev than in the U.S. so they like to show up there thinking it will transfer back to the U.S. Of course any popularity they have is the same old-same old dem tactic -ie. show up with the cash and start doing the Santa Claus routine. Not sure that will work all the way up to the midterms when people get tired of the Build Ukraine Back Better Routine and are trying to make Ukraine the 51st state while Americans descend into the poorhouse. Boris and Macron have both done the same in their own ways with their domestic problems. Ukraine War is the best thing that ever happened to them.
