Trump responds to Super Tuesday

This morning, as Haley was dropping out, Trump sent a message over his social media platform Truth Social reacting to the results:

"Nikki Haley got TROUNCED last night, in record setting fashion, despite the fact that Democrats, for reasons unknown, are allowed to vote in Vermont, and various other Republican Primaries. Much of her money came from Radical Left Democrats, as did many of her voters, almost 50%, according to the polls. At this point, I hope she stays in the "race" and fights it out until the end! I'd like to thank my family, friends, and the Great Republican Party for helping me to produce, by far, the most successful Super Tuesday in HISTORY, and would further like to invite all of the Haley supporters to join the greatest movement in the history of our Nation. BIDEN IS THE ENEMY, HE IS DESTROYING OUR COUNTRY. MAKE AMERICA GREAT AGAIN!!!"

Haley quotes Thatcher and thanks the women and girls who supported her campaign

In her short remarks, Haley quoted Margaret Thatcher: "Never just follow the crowd. Always make up your own mind." She used this quote to encourage the likely nominee, Trump, to appeal to the primary voters who he hasn't won over. She also thanked the girls and women who have supported her campaign, as another (subtle?) reminder of her historic run.
