It's the largest battleground state this year, and polls suggest the margin of victory will be 1% or less.As expected, both Biden and Trump won their Pennsylvania primaries overwhelmingly, but there were some ominous signs for both in the results.

Nikki Haley, a former Republican presidential candidate who dropped out of the race following Super Tuesday in early March, managed to score almost 17% of the vote against former President Trump in Pennsylvania.

Nikki Haley garnered 17% of the vote in Pennsylvania’s Republican primary despite having dropped out over a month ago. Her double-digit performance in the swing state is seen by some as a potential warning sign for former President Donald Trump — the party’s presumptive nominee — who won 83% of the vote in the April 23 primary.

When Nikki Haley suspended her presidential campaign, she refused to endorse Donald Trump for the 2024 Republican nomination — and apparently so did some of her supporters in Pennsylvania.

More than 16% of Pennsylvania's GOP primary electorate supported the former South Carolina governor over former President Donald Trump, the party’s presumptive nominee.

U.S. President Joe Biden and Republican challenger Donald Trump on Tuesday easily won their primaries in the battleground state of Pennsylvania according to Edison Research, but thousands cast votes for former candidate Nikki Haley.

A sizable share of Republican primary voters in Pennsylvania cast a ballot for former UN Ambassador Nikki Haley on Tuesday, despite former President Trump clinching his party's nomination over a month ago.
