  Consider an Galton Watson tree of height $m$: each leaf has one of $k$
opinions or not. In other words, for $i \in \{1, . . . , k\}$, $x$ at
generation $m$ thinks $i$ with probability $p_i$ and nothing with probability
$p_0$. Moreover the opinions are independently distributed for each leaf.
Opinions spread along the tree based on a specific rule: the majority wins! In
this paper, we study the asymptotic behavior of the distribution of the opinion
of the root when $m \to +\infty$.
