Obama's the grown-up-in-chief or something

Don’t look for the president to focus his guns on other primary candidates the way he did Trump. That would make it too easy for his opponents, and Obama and his team are happy to watch the field eat itself…

Whoever does emerge to take on Obama will receive the same lessons Trump did: Obama is a fierce campaigner, and the nation’s grown-up-in-chief has little patience for sideshows.

The man running for another four years in the White House is no joke. If Republicans want to win, there had better not be any confusion about whether their candidate is. Otherwise, as he has done before, Obama will have the last laugh.
