ARLINGTON, Va. (AP) — President Joe Biden is campaigning in Northern Virginia for Democrat Terry McAuliffe in a governor’s race that looks to be extremely tight just a week before Election Day. Biden carried Virginia by a comfortable 10 percentage points just last fall, but his approval ratings have been sagging. Polls have shown McAuliffe tied with Republican former business executive Glenn Youngkin. A loss by McAuliffe would be an ominous sign for Democrats. They are already likely facing stiff political headwinds in next year’s midterm elections, when their narrow control of Congress is at stake.
