Trump-backed Republican defeated

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 yesterday, 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 percent to 45.1 percent.

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 favorite in Alabama's special election to be held in December against Democratic nominee Doug Jones.
