Chelsea Clinton rallied Nassau County Democrats on Friday on behalf of her mother, Democratic presidential candidate Hillary Clinton, calling the race “the most important presidential election of my lifetime.”

Chelsea Clinton spoke for more than 45 minutes to about 100 women in Sands Point.

Clinton touted her mother as an experienced leader who would focus on issues including gun control and climate change, while reaching across the aisle to work with Republicans.

“It matters that people are able to find common ground and don’t mistake purity for progress,” said Clinton, vice chair of the Clinton Foundation.

Clinton, of Manhattan, cited her mother’s work as a U.S. senator from New York to increase funding for early childhood education and health care for low-income children.

She also noted Clinton’s work as secretary of state to fast-track asylum for lesbian, gay, bisexual and transgender activists who are discriminated against overseas.

Chelsea Clinton also criticized her mother’s Democratic opponent in Tuesday’s Democratic presidential primary, Sen. Bernie Sanders of Vermont, for offering narrow policy views.

She noted that during Thursday’s Democratic debate in Brooklyn, Sanders discussed the need to fill a vacant Supreme Court post with a justice who would vote to overturn the Citizens United court decision that allowed unlimited spending by super PACs on ads in federal political races.

Hillary Clinton also has said she wants to see Citizens United overturned, but her daughter said the selection of the next Supreme Court justice cannot be based on a “single issue.” She said the next Supreme Court justice will be responsible for voting on a wide slate of critical issues, including abortion rights, voter ID laws and gun control laws.

“My mother is the only person running who can really help us navigate through this time,” Clinton said.

Clinton said Republican presidential candidate Donald Trump has offered a “daily diet of hate speech” at his rallies.

She also attacked Trump’s plan to build a wall on the U.S. southern border and a proposal by Sen. Ted Cruz (R-Texas) to boost police surveillance in neighborhoods with significant numbers of Muslims.

“That’s not the country I want my children to grow up in,” she said.

The event was held at the home of labor arbitrator Martin Scheinman, who has handled binding arbitration for law enforcement unions in Nassau and Suffolk.
