As some politicians opt to lay down their swords and acquiesce to the tour de farce that is Donald Trump’s presidential campaign, Senator Elizabeth Warren is stepping up her attacks, engaging in yet another Twitter battle with the presumptive Republican nominee Thursday night.

The Massachusetts senator’s late-night attacks on Trump—who, in one of his least creative and most adorable attacks branded her “Goofy Elizabeth Warren”—are nothing new; the progressive Democrat consistently hits Trump on his xenophobic bullying and “embarrassing insecurities.”

Warren’s position as an attack dog against Trump could be a useful weapon to Democrats moving forward, just as her progressive ideology could help mend the rift between Hillary Clinton and Bernie Sanders supporters before the November election. Warren is popular among the very people Clinton is trying to court, and the Massachusetts senator’s endorsement could be instrumental to increasing the former Secretary of State’s rapport with progressives hesitant to back a self-proclaimed moderate.

Clinton supporter Sen. Tim Kaine said Warren’s “validation of Hillary at the right time will help bring everybody together.” He added he’s “fairly confident” she’ll endorse the Democratic frontrunner.

Regardless of whether Warren’s all-in for Clinton, we can certainly expect the senator to continue on her crusade against Trump. And for that, we are eternally grateful.
