President Donald Trump is in West Virginia on Tuesday — a state he carried with 62 percent of the vote in 2016 — to campaign for the state’s Republican attorney general, Patrick Morrisey, who seeks to unseat incumbent Democrat Sen. Joe Manchin.

In a tweet that left no doubt about his commitment to seeing Morrisey through to victory in the state that has gone increasingly Republican in recent years, Trump said: “Will be going to the Great State of West Virginia on Tuesday Night to campaign & do a Rally Speech for a hard working and spectacular person, A.G. Patrick Morrisey, who is running for the U.S. Senate. Patrick has great Energy & Stamina — I need his VOTE to MAGA. Total Endorsement!”

The rally, which is expected to draw a standing room-only crowd, begins at 7 p.m., but people began filling seats three hours before the official start of the event at Charleston’s Civic Center.

Manchin, a moderate Democrat who was previously the state’s governor, is currently ahead of Morrisey in the polls by 5-7 points, but Trump has compiled an enviable record of using endorsements to help favored Republicans.
