I don't have a problem with likeability as a factor. It's a very important quality for someone whose primary job is to use the bully pulpit to make us all feel good. That's partly what made Reagan and Clinton successful. Hillary just doesn't have it. People don't trust her. She doesn't impress me as sincere, or even a nice person. She doesn't seem to handle criticism well, which is terrible for someone who must make many decisions with the help of advisors. And this is without even looking at her political views. I'm not sure how she pulls it off in the general, unless Republicans nominate someone equally as polarizing (like Newt).
I disagree.
For all his later flaws, Nixon had qualities as a politician, and a pragmatic.
But he was beaten by Kennedy, because he lacked charisma and good looks.
In the famous TV debate, those who saw the debate thought Kennedy won, but those who only heard it on the radio, thought Nixon won it.
And thanks to that debate, and probably some cheating, Kennedy won.
This is a problem IMO.
Would FDR ever have been able to win the presidency with his weak health?
Media is largely responsible for the focus on likeability.
Also, a big problem is that a lot of the candidates fortunes is decided, not by the political platform, but by the cashflow generated.
How many great potential US presidents have we missed out on?
I know we've at least had one great: FDR.
Other than him, there's been a few good ones, but not anyone who probably the best man in the nation at the current time.
