Electoral Map Is a Reality Check to Donald Trump’s Bid

Mr. Trump has become unacceptable, perhaps irreversibly so, to broad swaths of Americans, including large majorities of women, nonwhites, Hispanics, voters under 30 and those with college degrees — the voters who powered President Obama’s two victories and represent the country’s demographic future.

.. “In the modern polling era, since around World War II, there hasn’t been a more unpopular potential presidential nominee than Donald Trump.”

.. If Mrs. Clinton somehow loses the Democratic race — unlikely given her delegate advantage — Mr. Trump could fare even worse in a general election against Senator Bernie Sanders of Vermont, who has higher margins than Mrs. Clinton in head-to-head polling against Mr. Trump in most swing states.

.. There are likely to be around 30 million votes in this year’s Republican primary once all 56 states and territories finish voting in June. In the 2012 contest between Mr. Obama and Mr. Romney, about 129 million voters cast ballots.
