There's an old political saying that presidential candidates appeal to their parties' wings -- left for Democrats, right for Republicans -- in the race for the nomination and then appeal to the center in the general election campaign. It was put in canonical form by Richard Nixon, one of only two Americans our major parties nominated for national office five times (the other was Franklin Roosevelt).
The dozen or so already announced Democratic candidates seem to be following Nixon's rule, and with more reckless abandon than Nixon ever did. Maybe they figure that whoever gets the Democratic nomination will inevitably beat Donald Trump. After all, no one they ever talk to would vote for him.

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
