"For anyone who has ever felt counted out, overlooked, and underestimated, I hope you know that the impossible is still possible," Alsobrooks, who had the support of most major players in the Maryland Democratic Party apparatus, told supporters during a victory speech on Tuesday night.
She vowed to defeat the Republican nominee for the seat, former two-term governor Larry Hogan, and said the Democratic Party was "united in our focus to keep the Senate blue."
Political observers took note of the unexpected margin of victory as well as the dynamic of Trone's outsized spending.
"So…. Not a single poll had Alsobrooks winning by anywhere close to double digits, elections absolutely can break late, and campaigns matter," said Colin Seeberger, senior communications director for the Center for American Progress. "Feels like there are some lessons to be learned here for, I don't know, future elections."
Fight Corporate Monopolies, a progressive advocacy group opposed to concentrations of corporate power, opposed Trone based on his fealty to monopoly interests during the primary and called him "just another billionaire bully who thinks he can buy himself a Senate seat."
The group ran one ad comparing Trone to former president Donald Trump and documenting his attacks on rival small businesses and workers:
Following Tuesday's defeat, Faiz Shakir with Fight Corporate Monopolies, said: "I believe [our] ad against Trone—both in timing and in message—played a key role in changing the trajectory of the Senate race."
John Nichols, veteran political reporter for The Nation, said: "Maryland Democratic voters rejected mega-rich corporate monopolist David Trone in their Senate primary and instead chose highly qualified Prince George's County Executive Angela Alsobrooks to take on Republican Larry Hogan. Good move."
