Strongly disagree. Politicians mostly want to be re-elected, not to be blamed for bad events, not to be kicked out by their own party for becoming an electoral liability... gaining some trust/confidence from the public can make all the difference to whether a politician is seen as coping with a difficult situation or blamed for it. Some of them even want to achieve more than just being in power, and trying anything new/bold also requires some faith from the voters.

He didn't just do his old fumbling for words thing in the debate, he wasn't able to participate coherently in the debate at all. It was a disaster. Persuading the electorate to have confidence in you is a large part of a politician's job and he failed.
