Raw Story has an article that should bring a little relief here. In it, Frank Luntz the conservative pollster says he does not believe that Trump will gain voters from this attack: link here: Conservative pollster slaps down belief Trump will add voters after assassination attempt
A couple of excerpts:
Late Saturday night, Luntz took to X to proclaim, "In the end, voters will settle down and return to their candidate of choice. The people who move towards Trump out of sympathy will probably move back."
But its not all good news:
He then elaborated, "But what happened in PA will definitely impact the final vote, guaranteeing that every Trump voter will actually vote. Biden, or any other candidate the Democrats put up, will not have the same participation certainty. That participation gap is worth at least 1% and as much as 2%. And because it happened in Pennsylvania, the impact will be highest in Pennsylvania."
So, we just have to motivate the anti-Trump vote a little more.
