I have long sensed that the 2016 California primary would be very memorable.

Kemberlee Kaye just reported that Donald Trump and Bernie Sanders may debate ahead of the California primary, as Hillary Clinton declined to debate Sanders recently.

Hillary Clinton may want to rethink the non-engagement approach that led to this development, as Sanders is now closing the gap in recent polling.

The Public Policy Institute of California (PPIC) poll, conducted May 13 – 22 and released Wednesday, found: “Among Democratic primary likely voters, 46 percent support Clinton and 44 percent support Sanders. These voters include Democrats and independents who say they will vote in the Democratic primary. Clinton has a slight lead over Sanders among registered Democrats (49% to 41%).”

The reason I highlight “Democratic primary likely voters” is that many Republicans are re-registering in order to vote #NeverHillary in June. Dawn Wildman, coordinator of California Tea Party Groups, indicate that several Democratic Party activists have reached out to her, attempting to encourage this voting pattern.

“What is interesting is that these Democrats say they will vote for Trump in the fall,” said Wildman. “They were surprised when we didn’t hang up on their proposal, but noted that many our members were already moving forward with this voting plan.”

Think about it: The Democrats “inevitable” nominee had a 11-point lead in January of this year, and now is essentially in a dead-heat with someone who has not regularly identified as a Democrat before tossing his hat into the ring.

One of the most surprising aspects of this poll is just how narrow the gender gap is, as well as the small difference in the Hispanic vote preference.

Sanders holds a 4-point edge with men, and Clinton leads by 7 points among female voters.

There’s also little difference between white voters, who favor Clinton by a 6-point margin, and Hispanics, who back the former secretary of state by 9 points.

A win in California would give Bernie Sanders a reason to press superdelegates to change their convention intentions.

Interestingly, Sanders’ position on Superdelegates has… evolved.

Bernie Sanders’s suggestion that he might fight for the presidential nomination all the way to July’s Democratic National Convention runs counter to the position he adopted in 2008.

Now, Sanders’s aides argue that only pledged delegates, not superdelegates, should be counted when weighing support for him and front-runner Hillary Clinton. But in 2008, Sanders backed then-Sen. Barack Obama as the presumptive nominee even though Obama too lacked enough pledged delegates to win outright.

Sanders continues to be greeted by massive and enthusiastic crowds during his current tour, including today’s stop in Ventura:

If Sanders closes once San-Andreas-sized gap in California completely, and pulls out a win, there will be political tremors felt all the way to Philadelphia this summer.
