Legally speaking there is nothing wrong with 'buying' politicians. So long as the legal tender is offers - the kind Eugene and Balala got - nothing to be done. Even Dr Ben Carson is now a Trump cabinet secretary.
Now here of course some of the tender in supply would land people in prison if the judicial system was properly functional.
It says alot about our democracy that defectors shuffle weight around. We are free of principles. I think the US was this way in the days of the unforgiving wilderness - wild wild west.
