Myrna Blyth, a former editor of the Ladies' Home Journal, writes about Hillary Clinton in the National Review Online. Blyth compares Hillary to Bill. She sees plenty of ambition in Hillary but little likeability, whereas Bill has both. And she argues that the more we see of Senator Clinton, the less we feel comfortable with her.
If you apply her test of "Do I like this person?" to the last two presidential races, it would appear that both featured seriously unlovable Democrats (Gore, Kerry) losing to a somewhat unlovable Republican (Bush). Bill Clinton and Ronald Reagan were probably the most recent candidates about whom many people thought "I like his public persona." Of course, people can be elected President without manifesting interpersonal warmth, for example Richard Nixon.
