How should I understand "political weakness"?

So, President Truman and other party leaders discussed different candidates. Each one, however, seemed to have some political weakness.


Some problem in the area of political activities and/or political ideas that would make it difficult for them to achieve success.

Shahak's footnotes were most of the time very logical, but not
necessarily convincing, pointing to one of his main political
: as an extreme rationalist - he addressed human beings from
the point of view of rationality and logic only.
He failed to take
into consideration all the irrationality that exists in human beings,
especially in dealing with ideological issues, and the need to develop
educational ways, to gradually change the misconceptions of others by
speaking to their hearts and not only to their minds.
