Poll shows 37 percent of voters think Trump is currently running the better 2024 campaign, compared to 36 percent for Biden.

In 30 years of Senate bids, Mr. Biden was such a formidable incumbent that he did not face a serious threat to his return to office. His last re-election is shaping up to be something different: a fight.

Joe Biden and Donald Trump are two presidents with unfinished business and an itch to get it done. Their track records and plans on abortion, immigration, taxes, wars abroad — you name it — leave no doubt that the man voters choose in November will seek to shape the landscape of American life in ways wholly distinct from the other.
