Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Why are Republican billionaires turning their back on Trump and not giving him money?

 It is not clear why some Republican billionaires may be turning their back on Donald Trump and not giving him money for his 2024 campaign. There could be many reasons for this, such as disagreements over policy, concerns about Trump's leadership style, or a desire to support other candidates. It is also important to note that it is not uncommon for political campaigns to rely on donations from regular Americans, and it is not necessarily a sign of weakness or a lack of support.
