Ah, election season. It's a time when corporate Democrats endorse ideas that they've spent a lifetime fighting against, so that they can get the votes of people they hold in contempt.

Normally Senator Feinstein doesn't even bother to do that because of her massive warchest, consistent endorsements by the party establishment and news media, and support by moderate Republicans makes her immune.

But this year is different.
This year she is feeling pressure from progressives.
Thus she is temporarily changing her positions on multiple issues that she's held for a lifetime in office.

Legal marijuana:

Sen. Dianne Feinstein (D-Calif.) said Tuesday that she is open to extending federal protections for states that have legalized recreational marijuana.
Feinstein, a longtime opponent of legalizing marijuana, also said that while California has approved the recreational use of the substance, the state needed to "ensure we have strong safety rules to prevent impaired driving and youth access, similar to other public health issues like alcohol.

Death Penalty:

California U.S. Senator Dianne Feinstein says she no longer supports the death penalty, a significant policy shift as she seeks re-election against a Democratic challenger.

Feinstein says it's become clear to her that the death penalty is applied unequally and not an effective deterrent.

Feinstein's support for the death penalty played heavily in her 1990 campaign for governor. She won the Democratic nomination despite being booed by activists at the California Democratic Party's convention for her stance. She ran television ads noting that she was the only Democrat backing the death penalty. She lost the general election.

Medicare for some:

In the past month, California Sen. Dianne Feinstein has thrown her support behind two liberal health care bills. Shortly thereafter, her re-election campaign began airing a statewide ad touting her embrace of the policies promoted by the two bills she co-sponsored.

"I believe in universal health care, in a public health option to compete with private insurance companies and expanding Medicare to everyone over 55," Feinstein says in the ad, part of an attempt to push back against her leading 2018 opponent, state Sen. Kevin de León, who has made his support of a single-payer health care program a central plank of his campaign.

Feinstein is still comfortably in the lead, but the fact that she's shifted for the first time on so many issues tells me that this poll doesn't tell the whole story.
