Hillary back on track

After the post-Iowa wobble, Hillary Clinton has regained a 13-point national lead over Barack Obama in the latest CNN poll - a higher lead than she enjoyed on that poll in December. More interestingly, Democratic voters are significantly more enthusiastic about a Clinton candidacy than they are about the prospects of an Obama candidacy, and far more enthusiastic than the Republicans are about their potential candidates, including John McCain. Clinton would also beat all the Republican candidates, including McCain. Her comeback is complete (though Obama is still likely to win South Carolina).
