Alabama GOP Senate candidate Roy Moore rode up to his polling place on horseback Tuesday morning to cast his vote in a special election that has improbably electrified the nation.

With a cowboy hat perched on his head, Moore, 70, hit the polls several hours after President Trump hissed another full-throated endorsement of the accused pedophile.

“The people of Alabama will do the right thing. Doug Jones is Pro-Abortion, weak on Crime, Military and Illegal Immigration, Bad for Gun Owners and Veterans and against the WALL. Jones is a Pelosi/Schumer Puppet. Roy Moore will always vote with us. VOTE ROY MOORE!” tweeted the commander-in-chief, who is facing his own renewed round of questions over allegations of sexual misconduct.

Moore is facing off against Jones, a former federal prosecutor and a Democrat, in a Cotton State contest to fill the Senate seat vacated by Attorney General Jeff Sessions.

With Republicans holding a narrow 52-48 lead in the Senate, the GOP and Trump see Moore’s election as crucial to advance the president’s agenda.

At least eight women have charged that Moore sexually harassed or abused them, including two who allege that he groped them when they were teens and he was a local district attorney in his 30s.

Like Trump, Moore has branded all of his accusers liars.

The polls close at 8 p.m. New York time.
