Fox News poll has Sanders ahead of Clinton nationally, and both ahead of Trump

Powerline reports:

Clinton has gone from 28 points ahead of Sanders to just 3 points up in one month, a shift of minus 25 points (send those flowers to Madeleine Albright and Gloria Steinem, Senator Sanders). Among whites, Clinton has experienced a shift of minus 13 points. The two groups among which her support has basically held steady are black voters and those with a college degree.

The message is clear. Blue-collar white Democrats — the cohort that fueled Clinton’s late charge against Barack Obama in 2008 — are defecting at a rapid rate.

What a poll.
