Political polls are notoriously unreliable, but I’m going to point to the results of two new ones anyway that show a collision ahead between two polarizing candidates for the Democratic presidential nomination.

According to the Los Angeles Times, a new UC Berkeley Institute of Government poll shows Sen. Bernie Sanders (I-Vt.) pulling away from the field in California. Sanders is at 26% and rising, while his nearest rival, Sen. Elizabeth Warren (D-Mass.), is at 20% and fading (with a margin of error of 2.5 percentage points).
