These are basically "what polls show now"; obviously, things will change and these will look hilarious in the actual 2017.
Just like reading through the 2004 threads where John Edwards was cited as the "future of the Democratic Party."
...president of the United States? Joe Biden, D! (but seriously, I get the feeling things are going to change and prevent Christie, Paul, or Clinton from winning their parties' primaries, and c'mon, Biden SNL spoofs would be even better than the Bush II ones.)
...chancellor of Germany? Angela Merkel, retained Rösler for CDU/FDP coalition
...president of France? Jean-Francois Cope, UMP
...prime minister of the UK? Ed Miliband, Labour
...prime minister of Canada? Stephen Harper, Conservative
...prime minister of Australia? Heck if I know.
