There’s Plenty Of Time For Trump Or Clinton To Become Likable Enough

From FiveThirtyEight:

Donald Trump’s favorable rating is now roughly equal to Hillary Clinton’s favorable rating.

Jimmy Carter was very unpopular in 1980 before the conventions, but saw his net favorability rise 24 percentage points by the time they were over, basically matching Ronald Reagan’s rating (Reagan’s fell during the convention period).

John McCain suffered a similar fate in 2008. After a strong convention, and the initially successful rollout of his running mate, Sarah Palin, McCain got an 8 percentage point bump; then-Sen.Barack Obama’s …
