Evidence is mounting that Russia took 4 clear paths to meddle in the US election

The first involved establishing personal contact with Americans perceived as sympathetic to Moscow — such as former Defense Intelligence Agency chief Michael Flynn, former Trump campaign chairman Paul Manafort, and early Trump foreign-policy adviser Carter Page — and using them as a means to further Russia's foreign-policy goals.
The second involved hacking the Democratic National Committee email servers and then giving the material to WikiLeaks, which leaked the emails in batches throughout the second half of 2016.
The third was to amplify the propaganda value of the leaked emails with a disinformation campaign waged predominantly on Facebook and Twitter, in an effort to use automated bots to spread fake news and pro-Trump agitprop.
And the fourth was to breach US voting systems in as many as 39 states leading up to the election, in an effort to steal registration data that officials say could be used to target and manipulate voters in future elections.
