Any speech by any politician ha sto be listened to very carefully. Most of the time they don't out right lie. Every word and phrase has to be parsed. After the speech is over the political experts tell us what was meant. We then believe them instead of relying on our own ears intelligence. Example "we need to invest in this or that" do you know what Invest means to a politcian? It means taxes are going up.
Or when a politico is asked a question about when he/she knew something or did or didn't do something they will answer "there is no evidence that I did/didn't do it". The experts will then explain that he/she denied the allegation. Did he really?
