(Bloomberg) -- The increasingly crowded field of Republican presidential contenders became more combative toward frontrunner Donald Trump with the addition of former Texas Representative Will Hurd.

A moderate from a swing district along the border with Mexico, Hurd launched his campaign by calling Trump a “lawless, selfish failed politician” who cost Republicans in 2020 and 2022 and would get President Joe Biden reelected in 2024.

Other long-shot candidates, including former New Jersey Governor Chris Christie and — to an extent, former Vice President Mike Pence — have also taken more direct aim at Trump, while the top challenger, Florida Governor Ron DeSantis, has intermittently sparred with Trump while shying away from overt fights.

Strategists see a larger field benefiting Trump, who can rack up delegates with a strong plurality of voters, while challengers with lower poll numbers struggle to get the publicity and donations to stay in the race.
