Here we go again: President Biden has just announced his 2024 reelection bid. But has his time in the White House actually convinced voters to give him another four years? Or are even his supporters turning “blah” for Biden?   Read more: The video starts out dramatically. Images of the Capitol under attack on Jan. 6, 2021. Grainy footage of a protest on the grounds of the Supreme Court. A musical score to rival a Marvel superhero movie. And then President Biden’s voice, announcing his 2024 campaign: “Freedom. Personal freedom is fundamental to us as Americans. That’s been the work of my first term. To fight for our democracy,” he says, music soaring under the voice-over of the launch video. “This is not a time to be complacent. That’s why I’m running for reelection.” But as the campaign tries to ratchet up excitement for the president’s reelection bid, the roadblocks to another four years are also mounting. Rising inflation. Stagnant legislative attempts. And, maybe most importantly, an enthusiasm gap from voters — even the people who supported Biden in 2020. White House reporter Tyler Pager joins “Post Reports” to give a snapshot of the country — and a president — in the run-up to 2024.
