Potential challengers to Kamala Harris are uniting behind her

Less than a half-hour after posting his announcement that he would not continue his campaign for a second term, President Joe Biden put out a second statement, in which he fully endorsed Vice President Kamala Harris as the next Democratic nominee.

However, several other names have been tossed around as potential contenders over the last few weeks. If some in the party get their wish for some form of open convention or “mini-primary,” those may be the names involved.

Whether Harris moves directly into the role of Democratic nominee or has to fight for that position could be as significant to the party’s chances in November as Biden’s decision to stand aside. Potential rivals to Harris’ position as nominee are largely the most common, traditional sort of presidential candidates—governors. But there are others in Congress—and even within the Biden administration—whose names are being suggested.

Here’s what we know about the decisions of some of the names that more frequently appear on the list of possible contenders.
