Could be false. The stimulus is restricted to politicians who do not support extending free trade to other Latin American countries. We do not have any information about politicians who do support this idea.

Could be false. We don’t have any information to infer whether these politicians have changed their position. It is possible that these politicians have never supported the idea of extending free trade to Latin American countries.
