Incumbent Democratic President Joe Biden and his Republican predecessor Donald Trump faced off in three states' primaries on Tuesday, further cementing their expected 2024 rematch.

In Maryland, Biden got 86.3% of the vote with 67% of ballots counted.

The uncommitted campaign – tied to protests over the Biden administration's support for Israel's siege of Gaza – accounts for 10.4% of ballots cast in the Democratic primary.

Marianne Williamson, who suspended her campaign before reentering the race earlier this year, got 2%.

Trump won 80% of the GOP vote with 83% of ballots counted. Nikki Haley, who dropped out of the race after Super Tuesday, got a whopping 20%.

Nebraska saw Biden win 90% of the vote with over 95% of ballots counted. Congressman Dean Phillips, who has suspended his campaign and endorsed Biden, got 10%.

In the Republican primary, Trump came out with 80.2% of the vote, while 17.9% went to Haley.

West Virginia saw Biden take 70.5% of the Democratic primary vote with over 95% of ballots tallied.

Things took an unexpected turn from there, as relatively unknown Democratic candidate and businessman Jason Palmer – who made headlines for winning American Samoa's Super Tuesday primary – brought home 11.5%. Even less-known retired US Army General Stephen Lyons scored 7.6%.

In the Republican primary, Trump took 88.4% of the vote. Haley won 9.4%.

The tallies gave both Biden and Trump a boost as they approach a likely rematch on November 5. At the same time, they signal that many Americans are less than thrilled with the two establishment party picks.
