Trump for President: Who’s laughing?

A regular sketch included ‘news of the future’ and one famous 1968 episode imagined the future 20 years on with Ronald Reagan as US President. The idea was so laughable that it was thought it could never happen, but it did.
Likewise Donald Trump. It is not so long ago that the thought of him entering the White House was unthinkable but, after his success in the Super Tuesday primaries, Trump is well on his way to receiving the Republican nomination.
