Latest New Hampshire poll from Suffolk University. Trump leads by 17 points. With DeSantis out and endorsing Trump, Trump will probably gain even more on Haley. Most of DeSantis' supporters had Trump as their second choice. Haley doesn't really have a shot at this point.
I think the question at this point will be if Haley drops out before being embarrassed in South Carolina. Trump has a 40 point lead in her home state.
I would like her to actually ride it out until the convention. The Never Trumper can at least force him to keep making campaign appearances... run him ragged and exhausted on primaries. The more tired he gets, the more cracks will show.
