President Joe Biden’s latest campaign swing has taken him to Nevada, where the first-in-the-West primaries are underway with early and absentee voting. But the Democrat is also using the visit to shore up support for the general election. Biden arrived in Las Vegas on Sunday for appearances through Monday, including a campaign event to rally supporters to vote in the state's Democratic primary on Tuesday. But the campaign is also looking to drive momentum for the general election as a rematch with Donald Trump seems to be shaping up. Biden won Nevada in 2020 by fewer than 3 percentage points over Trump.
