Democrats open their convention transformed by Harris' ascendance but facing lingering questions

CHICAGO (AP) — A refreshed Democratic Party reintroduces itself to a divided nation this week, having been transformed by the money, momentum, relief and even joy that followed Vice President Kamala Harris ' rise to the top of its ticket.

The whiplash of the last month culminates in a convention that begins Monday in Chicago. Above all, the four-day gathering of thousands of activists and party leaders from across the nation is designed to celebrate and strengthen Harris as President Joe Biden's replacement and boost her campaign to defeat Republican Donald Trump in November.

Just beneath the surface, real questions loom about the depth of Harris' newfound support, the breadth of her coalition and the strength of her movement. Not even a month ago, Democrats were deeply divided over foreign policy, political strategy and Biden himself, who was holding on after his disastrous debate by suggesting he had a better chance than any Democrat — including Harris — of beating Trump.

Far from the formality that many modern party conventions have become, this week's event will bring many Americans their first extended look at Harris and her new running mate, Minnesota Gov. Tim Walz. How the Democrats present Harris and Walz will be critical, especially with Trump launching a weeklong effort to cut into their message.
