> valid arguments are very few; but the list of logical fallacies is long (and rather exciting). Alas, politicians seem to prefer the latter....

Because politics isn't about finding facts or acting in the most logical manner.

It's about *winning,* and if that takes appealing but fallacious arguments (and it does) those are the arguments we'll get. Hence propaganda.

Propaganda techniques are essentially deductive fallacies, invalid inferences, bias, suppression of evidence ("cherry-picking"), and, of course, outright lies.
