California Gov. Gavin Newsom may be laying the groundwork for a 2028 White House campaign, but growing criticism from progressive activists inside his own state is creating fresh political challenges.
Rather than facing attacks from Republicans, Newsom is now under fire from environmental groups and left-wing organizations that accuse his administration of abandoning key climate priorities. The dispute highlights increasing divisions within the Democratic Party at a time when Newsom is widely viewed as a potential presidential contender.
Progressive Group Launches Campaign Against Newsom
Los Angeles advocacy organization Streets For All has launched a newspaper advertising campaign targeting Newsom in South Carolina and Nevada, two states expected to play a major role in selecting the Democratic presidential nominee.
The advertisements urge Democratic primary voters to closely examine Newsom’s record in California before supporting any future presidential bid.
The campaign represents one of the first organized efforts by progressives to challenge Newsom outside California, potentially complicating his national political ambitions.
California Climate Policies Spark Backlash
The controversy centers on recent changes to California’s cap-and-invest program, one of the state’s largest climate initiatives.
The program places limits on greenhouse gas emissions while requiring major industrial polluters to purchase emissions allowances. Revenue generated through the program helps fund environmental projects, public transportation improvements, affordable housing initiatives, and other state programs.
Environmental activists argue the latest revisions could significantly reduce the amount of money flowing into those projects.
Critics Say Billions Could Be Redirected
Several climate organizations object to a proposal that would allow certain companies to receive free emissions allowances if they invest in reducing their carbon emissions.
Supporters of the plan say the changes encourage businesses to modernize their facilities while preventing manufacturers from relocating to other states.
Critics disagree.
One financial analysis estimated the proposal could reduce cap-and-trade revenue by roughly $2 billion. Streets For All has characterized the policy as a major financial benefit for oil companies and industrial polluters while reducing funding for public programs.
The group’s newspaper advertisements accuse Newsom of redirecting billions of dollars that could otherwise support clean drinking water projects, public transportation systems, affordable housing, and other state priorities.
State Officials Defend the Decision
The California Air Resources Board (CARB), whose members were appointed by Newsom, has defended the revised policy.
Agency officials described the changes as a difficult balancing act between reducing emissions and protecting California’s economy. According to CARB, the goal is to keep major industries operating in California while continuing to pursue the state’s long-term climate objectives.
Officials argue that losing manufacturers to other states would not necessarily reduce global emissions and could negatively affect California workers and businesses.
Democrats Show Growing Divisions
The disagreement reflects broader tensions inside the Democratic Party.
While Newsom continues to promote California as a national leader on climate policy, several progressive organizations argue his administration has become too willing to compromise with large corporations.
The criticism extends beyond environmental policy. Some progressive activists have also opposed Newsom on issues including tax proposals, housing policy, and other major legislative priorities.
Those disagreements could become more significant if Newsom officially enters the 2028 presidential race, where Democratic primary voters often expect candidates to appeal to the party’s progressive base while remaining competitive with moderates.
Early Primary States Could Shape 2028 Race
South Carolina and Nevada remain two of the most influential early-voting states in Democratic presidential primaries.
By placing advertisements in those states years before the next presidential election, Newsom’s critics appear determined to shape his national image before any campaign officially begins.
Political observers have long viewed Newsom as one of the Democratic Party’s most recognizable national figures, making his record as California governor likely to receive increased scrutiny in the coming years.
Newsom Faces New Political Test
For years, Gavin Newsom has positioned himself as one of the Democratic Party’s most prominent national voices, frequently challenging Republican leaders and defending California’s progressive agenda.
Now, however, some of his toughest criticism is coming from within his own political coalition.
Whether those attacks remain limited to activist organizations or begin influencing Democratic voters outside California could become an important factor if Newsom ultimately launches a presidential campaign.
Newsom’s office had not publicly responded to the advertising campaign at the time this article was published.
