Washington • The big news in the Democratic presidential race is that not much has changed since Joe Biden jumped in.
To be sure, Massachusetts Sen. Elizabeth Warren has steadily gained ground, according to polls. California Sen. Kamala Harris rose sharply after the first debate but then gradually slid back into single-digit-land. Vermont Sen. Bernie Sanders has held onto his sizable base, while Mayor Pete Buttigieg has kept most of the support he won in his impressive spring debut.
But national and state polling shows that the basic shape of the race has remained the same.
