Rudy Giuliani's comment that there is "nothing wrong with taking information from Russians" has thrown a spotlight on an already raging debate in the United States about how far a candidate should go to win. While the Mueller report did not find that there was coordination between the Trump campaign and Russia, there is a wider issue of whether -- unwittingly -- candidates are helping malign foreign powers to achieve their goals.
In the fight against election meddling, we have seen the West start to act after years of denial and failure to cooperate against a common threat. Today, the USA has begun to talk to its allies, including coordination at the G7 level through a Rapid Response Mechanism, and at international, federal and state level there are measures being put in place, such as the EU adopting a code of conduct for web platforms, presidential threats to respond to meddling attempts, and greater coordination between US states to share information to protect ballot box integrity.
