You're absolutely right about the echo chamber thing, though u/Durumbuzafeju was pointing out the fact that they only got 54% of votes (and that's even lower proportion of the voting population's support since a large amount just didn't vote) despite having complete control over state media outlets (that is, parties in the opposition got 5 minutes each in total to demonstrate their campaign on state television) and having bought up many other formerly indepentent magazines and journals (see CEPMF). If, with all this spending and effort on exposure (having invested millions upon millions on CEPMF, Facebook and YouTube ads and so on), they still only get 3,000,000 votes in a country of 9.6 million, it really means that people aren't as supportive as it may seem at first.
