  In this paper, we study the interaction between the totally positive monoid
$G_{\ge 0}$ attached to a connected reductive group $G$ with a pinning and the
conjugacy classes in $G$. In particular, we study how a conjugacy class meets
the various cells of $G_{\ge0}$. We also state a conjectural Jordan
decomposition for $G_{\ge0}$ and prove it in some special cases.
