Well at least now Trump won't have to lie again about events where he was close to dying to gather the attention.
As for what this means for the sake of this election, it will surely give him a boost, but I don't know to what extent. Democrats are not going to flip to Trump over this and it is pretty unlikely that Republicans who have grown to hate Trump over the years will reverse course either.
This will for sure make a very high participation rate with Trumpists on election day but this is already a trait they do have.
Still, independents vote can favor Trump big time.
Now Democrats must go nuclear with everything popular, drop their passiveness and their ridiculous infighting.
