As someone who ran a hard-fought senate race against Elizabeth Warren in 2012, I dont agree with her on many policies, but Ihave togive her credit for her honesty aboutpolitical sensationZohran Mamdani.Asked about the New York City Democratic mayoral candidate this week, the Massachusetts senator urged her fellow Democrats to embrace Mamdanis socialistplans as the "Democratic message."Imagine that: a clear (albeit extreme) answer to a direct question rather than contrived talking points. Other Democrats are offering mealy-mouthed canned responses to questions about Mamdani, including my opponent in the New Hampshire Senate race, U.S. Representative Chris Pappas, D-N.H.,who wont take a positionon Mamdanis candidacy, and is calling me "pathetic" for raising the issue.TOP DEM SENATOR REVEALS SOCIALIST MAMDANI IS WHAT HER PARTY SHOULD LOOK LIKE: 'YOU BET'The outcome of this falls mayoral race in New York City has implications poised to resonate far beyondthefive boroughs. Not only would the epicenter of capitalism falling into the hands of an avowed socialist send a dangerous message to our innovators and the world, but it will shape the future of the Democratic Party struggling to find its footing. Less than a year after getting their electoral clocks cleaned by President Donald Trump, the partys national standing has plummeted to a35-year low.Republican candidates need to do more than sit back and watch the Democrats implode. We must loudly and clearly explain to voters what socialism means. Remind them its been decades since the fall of the Soviet Union, but a group of extreme and uniformed politicians are trying to bring back some of its core tenets. Mamdani has called for theabolition of private propertyand discussed "the end goal of seizing the means of production." These should be relics of a failed economic playbook that belongs in the history books, not modern political debates.Capitalism is the greatest force for good this world has ever seen. It has lifted people up from poverty and provided opportunities for those at the bottom. And I am one of them. Iwent frombeinga kid on welfare to the halls of Congress andthen toserving as President Donald Trumps ambassador to New Zealand and Samoa decades later.CLICK HERE FOR MORE FOX NEWS OPINIONThat upward mobility doesnt exist in Mamdanis socialist worldview. He frames his arguments around free handouts and government-run grocery stores. In his mind, its better to spread mediocrity widely than strive for excellence through hard work. Its free for everyone until it doesnt exist for anyone.Believe it or not, it wont be long before presidential candidates are kicking the tires on campaigns for 2028, especially in my home state of New Hampshire, the site of the First in the Nation presidential primary (at least on the Republican side, the Democrats decided to move itback in lineto boost former President Joe Bidens electoral prospects).Should he win this November, Mamdani is poised to become one of his partys biggest stars. His fellow socialist, Rep. Alexandria Ocasio Cortez, D-N.Y., is ascendant. Juan Williams, a well-respected Democratic voice even boldlypredicted this week: "Say hello in 2028 to President Alexandria Ocasio-Cortez."The copycat phenomenon is well underway. In Minnesota, a socialist challenger to the incumbent Democrat mayor has been dubbed the "Mamdani of Minneapolis."The recent trend lines are concerning. A2021 Gallup pollfound that just half of young Americans had a positive view of capitalism, while a separate survey showed that62%of younger voters held a "favorable view" of "socialism." The Occupy Wall Street movement that was born inmany ofAmerica'smajor cities a decade and a half ago has graduated to an open embrace of socialism.With President Trump atop the ticket, the GOP made steady gains last year amongyoungerandworking-classvoters. With every Democrat on record opposing tax cuts in the "One Big Beautiful Bill," not to mention provisions like "No Tax On Tips," we have a compelling story to tell about our vision for the future.If we dont, its more than just politics at stake. Its the future of our country. Democrats economic vision is the one outlined by Sen. Warren and Mamdani: more government programs funded by higher taxes. Unlike those twopoliticians, mostarent willing to admit it, but given the chance, their policies would be ruinous.CLICK HERE TO READ MORE FROM SCOTT BROWN
