A correct analysis of the mechanisms that lead ordinary Americans to support someone like Trump starts with the dysfunctionality of the political system and the general public’s growing distrust towards public institutions as well as traditional elites.
After all, as Mueller most emphatically reiterated during his hearing at the House of Representatives, there was and there continues to be Russian interference in American elections. Remedial legislative efforts to change this situation or reduce the system’s vulnerabilities are blocked by the Republican leadership in the Senate. The Russian operatives, as was clarified in Mueller’s report, hacked the Democratic Party and put the materials they stole on the Internet with the help of Wikileaks. The Trump campaign was happily aware of these activities and Trump himself encouraged the Russians and Wikileaks to come up with more material on his rival. There was also enough evidence in the report’s second volume that the President did indeed try to obstruct justice when the matter of Russian interferences in his campaign was being investigated. In fact, in Mueller’s own words, "the finding indicates that the President was not exculpated for the acts he allegedly committed".
