Nobody thought he was gonna win! Like I buy russia was trying to make the GOP more russia friendly. But this all presupposes that people legit thought trump was going to be president
Not necessarily - the Rosneft deal was going down with the aforementioned players regardless of Trump winning. In fact, Trump winning turned out to be more troublesome, because of what occurred during the election after the Mayweather event.
So, in that first foreign policy speech he made, Trump immediately starts calling for a peaceful coming together with Russia. And what you heard from a few GOP members in the lead up to the general (particularly from people who are implicated in that tweet narrative) is that we should be aiming for peaceful negotiations with Russia, not antagonizing them. This theory actually goes a long way to explain why Trump, a man supposedly with zero connections to Russia, would be arguing for peaceful business dealings with Russia in his very first foreign policy speech, when at that time everyone assumed the Middle East would be the biggest foreign policy topic of the 2016 GE.
If all they wanted was to pull the GOP/USA public perception on business dealings with Russia into a positive light, Trump could've easily done so while running in the GE, which is something he repeatedly & continuously tried to do. There is actually precedent for something similar in other elections, where a candidate takes on a seemingly logical stance that should receive majority support, only to pull their opponent more towards their stance. What really screwed these attempts up was the discovery of the Russian hacks on the DNC. This actually answers the question on why Russia would go through the trouble of hacking the DNC, then trying to hide any involvement and leaking it to Wikileaks - they didn't want the blowback to undermine the face-turn they had Trump trying to do in the GE.
