Robert F. Kennedy Jr. and Nikki Haley do not have a lot in common, but the cases they have made for choosing President Donald Trump over Vice President Kamala Harris are strong, and Trump should take the opportunity to campaign with both of them. The seriousness that this would add to his campaign, especially if he dropped the petty personal feuds that limited his appeal, could do much to regain the ground he has lost to Democratic nominee Kamala Harris.

Like Trump himself, Kennedy has always appealed more to those who consider themselves outside the party establishments. In his endorsement speech Friday, Kennedy aptly tied his struggles against the Democratic Party’s corrupt abuse of power to those also experienced by Trump.
