Democrats have strategically shifted focus, converting the narrative around age and competence into a critique against Donald Trump. Barack Obama has recently amplified these concerns by questioning Trump's readiness and mental agility for another term while campaigning for Kamala Harris in Arizona, a pivotal swing state. During a rally in Tucson, Obama highlighted these issues by humorously questioning if Trump's recent behavior, including his long, meandering speeches, indicated his capacity to govern.

"Have you seen him lately?" Obama quipped, further casting doubt on Trump's suitability for the presidency.

The Democrat strategy has been to challenge whether Trump, now the oldest presidential candidate in US history, possesses the vitality and mental acuity necessary for the office, especially following recent episodes where Trump appeared disoriented. Since Joe Biden, at 81, opted out of re-election, making way for the younger Kamala Harris, Democrats have found these attacks to be effective counterweights against Trump's own age advantages.

Just recently, events where Trump struggled posed questions about his stamina for leadership, leading Harris to challenge his ability to endure the arduous demands of campaigning. In Michigan, another key swing state, Harris questioned if Trump's campaign trail fatigue reflected his overall capability to serve. Harris, alongside influential figures like Obama and Michelle, endeavors to galvanize voters across select states critical to the forthcoming election.

With Arizona's slight edge favoring Trump, and Harris leading narrowly in Michigan, Democrats are pressing advantage wherever possible in their narrative. Their portrayal of Trump not only encompasses doubts about his health but also emphasizes a perception of danger, citing his past attempts to contest the 2020 election results. Obama's call to action in Tucson urged voters to consider the implications of Trump's continued leadership without the checks and balances he might attempt to override.

The Democrats' emphasis on Trump's alleged instability serves not just as a campaign message but as a broader appeal to the electorate's sense of democratic values.
