"Hey, if the guy from Maine can do well, I guess Hunter could do well, too, because the guy from Maine is a basket case," Trump added, referring to Maine Democratic Senate candidate Graham Platner. "And I would say worse than him is the one from Texas that looks like Alfred E. Neuman," referencing Democratic Senate candidate James Talarico.
Platner, a Marine veteran who has emerged as one of the party's fastest-rising political figures, has come under fire for controversies ranging from sexually explicit messages and offensive social media posts to a Nazi-linked tattoo and campaign staff upheaval.
Despite the criticism, Platner has retained the support of prominent Democrats, including Senate Minority Leader Chuck Schumer, D-N.Y., and Sens. Bernie Sanders, I-Vt., and Elizabeth Warren, D-Mass.
In Texas, Talarico has drawn pushback from conservative opponents over his use of his religious background, such as when he said "God is nonbinary" during a 2021 debate in the Texas legislature. In addition, he has previously said there are six biological sexes and referred to the radicalization of white men in an old social media post.
Hunter Biden's controversies involve his foreign business dealings, convictions for tax evasion and illegal possession of a weapon, and drug addiction.
