What to do about Russia? We, as policy, need to do what needs to be done to prevent any foreign nation from putting their thumb on the election process, so that their favorite candidate wins.
As for 'Hillary used all the guns at her disposal as well and got much help from the left slanted mainstream media constantly criticizing Trump," I seem to remember endless coverage of Hillary's emails instead of policy. When they weren't covering emails, a portion of the coverage was innuendo about the Clinton Foundation, that did nothing wrong. Trump's foundation's actual misdeeds weren't covered widely and were relegated to sources like NPR.
As for (uniformed) voters convincing themselves that Trump was somehow "anti-establishment," that turned out to be BS. While Trump railed that he would "drain the swamp" his cabinet is comprised of billionaires who tow the establishment line. He railed against HRC's ties to Goldman Sachs, then puts five of them in high office, including the cabinet. Trump's agenda and policies are identical to what the GOP establishment push.
The GOP establishment wants the ACA repealed and replaced by something that tosses tens of million of health insurance. That's exactly what Trumpcare does.
The GOP establishment wants environmental protections gutted. That's exactly what Trump did by nominating Tom Price as EPA head and gutting the environment by executive orders (that Trump objected to when Obama used them.)
The GOP establishment wants a hard stance against labor. Trump originally nominated Andrew Puzder, the CEO of the company that owns the Hardee's and Carl's Jr. Puzder withdrew facing high opposition. His approved labor secretary, Alexander Acosta, is not much better. The reality is that there isn't a hill of beans difference between right-wing establishment policies and the policies that Trump supports.
