Politico, please define “foreign policy observers”

In an article that portrays Vice President-elect Joe Biden as a goof (gee, where have we seen that unflattering meme before?) the Politico plays dumb and pretends it's very weird and bizarre that Biden is going on an overseas trip as chairman of the Foreign Relations Committee and before he's sworn in as vice president. Politico suggests the world leaders Biden meets with will be wildly confused by his presence.

Pretty thin gruel for a news story, which was highlighted by Politico's lame attempt to back up the non-story by claiming “foreign policy observers” are equally confused about Biden's trip.

Question: Who were the only two “foreign policy observers” Politco quoted for the anti-Biden article?

Answer: Two right-wing, partisan think tank employees.

One from the conservative American Enterprise Institute and another from the even more conservative Heritage Foundation. That's who Politico dialed up to get insightful, independent quotes about the Democratic VP.
