Of course, with all of this stuff, people have different sensitivities-- and I know there are some dialects where "which" regularly references a person. I actually might not notice the first occurrence myself, although on reflection it looks a little odd. The second one jumped out at me as seeming pretty weird, though.
Even so, I wouldn't correct it except that, read uncharitably, referring to a person with an inanimate term could be seen as somewhat insulting. Especially if you're writing about politics, it's probably worth getting right just to avoid that impression.
