An internal poll commissioned for Democratic activist Norman Solomon in California’s open 2nd district found him in position to advance beyond the June 5 primary, with several other Democrats close behind.

The race to replace retiring Rep. Lynn Woolsey (D) will most likely be between two Democrats under California’s new top-two primary format, in which two candidates no matter their party may advance to the general election.

Assemblyman Jared Huffman (D) led with 18 percent in the poll of 500 likely primary voters in the strongly Democratic district, followed by Solomon with 10 percent, Marin County Supervisor Susan Adams (D) with 8 percent and small-businesswoman Stacey Lawson with 5 percent. The remaining candidates, including both Republicans, took 3 percent or less, and 47 percent remained undecided.

The poll was conducted by Democratic firm Lake Research Partners from April 17 to 19 and carried a 4.4-point margin of error.

“Voters are largely undecided about the primary race, but Solomon is in second place in a crowded race,” pollsters David Mermin and Shilpa Grover said in a memo.
