The vice president has faced renewed calls from some pundits and columnists to be dropped from the ticket amid heightened concerns about the president’s age and doubts over her ability to lead if Biden were no longer able.

Biden won 61% of voters between the ages of 18 and 29 in 2020, making young voters a critical part of his coalition. However, his approval ratings within that age group now stand at 29% compared to 40% overall, according to a new AP-NORC poll.

Legal challenges to congressional districts also are ongoing in Arkansas, Kentucky, Louisiana, New Mexico, South Carolina, Tennessee, Texas and Utah. And new districts seem likely in New York and North Carolina, based on previous court actions.

If the current date holds, it would represent a setback to Trump’s efforts to push the case back until well after the 2024 presidential election, a contest in which he’s the early front-runner for the Republican nomination.

Republicans chose Milwaukee for the first debate and for the national convention in just 11 months largely because of Wisconsin’s well-earned status as a swing state. Four of the past six presidential elections have been decided by less than a percentage point.

The results underscore the new political reality, one that’s been repeatedly demonstrated in both blue and red states: Since the Supreme Court’s reversal of Roe v. Wade last year, abortion rights are a major, driving force.

Former President Donald Trump and Florida Gov. Ron DeSantis have dominated the early Republican race as the other candidates look for an opening to take them on. President Joe Biden faces a couple of Democratic challengers but is expected to secure his party’s nomination.

Moms for Liberty didn’t exist during the last presidential campaign, but the Florida-based nonprofit that champions “parental rights” in education has rapidly become a major player for 2024, boosted in part by GOP operatives, politicians and donors.

Republicans are poised to launch aggressive get-out-the-vote campaigns for 2024 that employ just those strategies, attempting to match the emphasis on early voting Democrats have used for years to lock in many of their supporters well ahead of Election Day.

The campaign will be the second for the former governor and federal prosecutor, who lost to Donald Trump in 2016 and went on to become a close on-and-off adviser before breaking with the former president over his refusal to accept the results of the 2020 election.
