What does "fillip of" mean in the below 4 sentences?
No.1,2, and 3 are usage examples from dictionaries. No.4 is from the internet

Well, what is shown below are the relevant definitions of fillip I have found from various dictionaries.
Oxford Dictionaries: something which acts as a stimulus or boost to an activity.
Cambridge Dictionary: something that causes a sudden improvement.
Vocabulary.com Dictionary: anything that tends to arouse
As you can see, fillip means along the lines of a boost or a stimulus. Only The dictionary by Merriam-Webster lists two additional meanings that might be helpful.
b a trivial addition c a significant and often unexpected development
However, I am still confused about the meanings of fillip in the above 4 sentences. For 1, does it mean that the tragedy may boost the support of the president? I have no ideas what fillip means in 2 and 3. For 4, does it mean a small/little boost of panic?
