Will Donald Trump endorse no one in the 2028 presidential election before Mar 1, 2028?

The question asks whether Donald Trump will endorse no one in the 2028 presidential election before March 1, 2028. The resolution criteria require a clear, affirmative public statement of support for a candidate specifically in the context of the 2028 election. As of the latest available information, Trump has not made any such endorsement. Article Aljazeera article explicitly states that Trump 'has not endorsed any candidate for the 2028 Republican presidential nomination' and that he denied a report of privately endorsing JD Vance. Article Ground article quotes Trump saying it is 'too early' to endorse Vance, reinforcing that no public endorsement has occurred. Article Post article notes that Trump has declined to clear the primary field for any candidate. These consistent reports indicate that, as of now, Trump has deliberately refrained from endorsing anyone for 2028. Given the early stage of the election cycle (more than three years before the deadline) and Trump's stated reluctance to endorse early, it is plausible he may continue this stance through the resolution date. However, there is a non-trivial chance he could change his mind and issue an endorsement before March 1, 2028, especially as the primary season approaches. The probability is set at 0.85, reflecting strong evidence of no endorsement so far and a reasonable expectation of continued non-endorsement, but with some uncertainty due to the long time horizon and potential future developments.
