The role of speeches

This thread is a spin-off from the Clinton vs. Merkel thread. In the latter, a consensus seems to be emerging that when it comes to the chances of women making a career in politics, the situations in the US and Germany seem to be more similar than different. In the present thread, I would like to pursue the role of speeches in the respective political cultures, where I perceive real differences. For my current thoughts, see my first comment.
