Interactions between which groups or individuals? A little more context would make this easier to answer. Certainly, the political conventions that took place during the 2016 presidential campaign are an example of political interactions. Both the Democrats and the Republicans held their own party conventions.
Meetings of groups such as the G-20 are another example of political interactions, this time between different nations. The G-20 is a collection of 20 of the major economies around the globe.
Finally, the electronic town hall is a modern twist on an old political concept. With advances in technology, citizens may participate in town halls via the internet rather than attending in-person.
