In our Campaign Trail Video of the Week, Stephen Colbert once again meets his match. On Monday night's episode of "The Late Show With Stephen Colbert," Mr. Colbert noted that Donald Trump "has resorted to almost cartoonish tactics" as his presidential campaign has faced recent setbacks. "So here now to comment on those tactics, please welcome Cartoon Donald Trump" -- back for a repeat appearance. (He arrives at 2:30 in the video embedded below.) This time, Cartoon Donald Trump -- who is just as entertaining as real Donald Trump and arguably slightly more presidential -- explained Trumpian math to Stephen Colbert.
