US President Donald Trump's pick in the Alabama Republican Senate runoff crashed to defeat Tuesday against a populist former judge, likely sending shockwaves through establishment Washington and denting the president's influence over his restless political base.
Perhaps sensing that, Trump quickly swung behind the winner, former Alabama state chief justice Roy Moore, calling him to offer congratulations.
"Sounds like a really great guy who ran a fantastic race. He will help to #MAGA!" Trump tweeted early Wednesday, referring to his "Make America Great Again" catchphrase.
The result, though, is an embarrassing setback for Trump that highlights the deep divisions within his party and raises questions about its future direction as the GOP heads toward mid-term elections in 2018.
It also signals that many in the grassroots conservative movement that helped propel Trump to the White House are still fighting against the party leadership and its grip on Washington politics during a turbulent period in which Republicans have struggled to deliver on key campaign promises like health care reform.
With all 67 counties reporting, Moore led incumbent Luther Strange by 54.9% to 45.1%.
Strange was appointed to the US Senate earlier this year to fill the seat vacated by Jeff Sessions, whom Trump picked to be his attorney general.
Moore hailed his win as a "conservative victory" for his state.
"Because of you, tonight, the establishment has been DEFEATED in Alabama!" he posted on Twitter.
Moore now becomes the heavy favourite in Alabama's special election to be held in December against Democratic nominee Doug Jones.
Trump offered his own congratulations to Moore, urging him in a tweet to "WIN in Dec!"
And several of Trump's past pro-Strange Twitter posts disappeared, according to a project documenting the president's deleted tweets by the news site ProPublica.
While Trump may be shifting his support to outsider Moore, the race in Alabama, in the heart of the Deep South, was the latest political battleground over the direction that the Republican leadership is taking the party in Washington.
The race was the stage for a proxy war of sorts between Trump and his recently ousted White House chief strategist Steve Bannon, who backed Moore.
