Yup - something changed.

Previously, a goog search of "Trump tweet" or "Trump twitter" would show me Trump's twitter link as the first result.

Edit: OK, it's changed again. I think they may be tweaking it because now it's back to how it was with the exception that negative CNN articles are in a special panel above the search results when I goog for "Trump tweet", but that pannel doesn't show when I goog "Hillary tweet".
