A formal endorsement from Edwards and his wife, Elizabeth, potentially could make a difference in that May 6 primary, especially if they decide to go out and campaign aggressively throughout the state during their final days. Both Edwardses remain very popular among the state’s Democratic base.
There have been intriguing hints that both John and Elizabeth Edwards are leaning in favor of Clinton, but they have avoided any formal announcement. John Edwards has declined most interview requests since dropping out of the presidential contest.
Earlier this month, Elizabeth Edwards, a cancer survivor, said she supports Hillary Clinton’s health care plan over the one put forward by Barack Obama.
“In order to ensure that we have universal coverage, we need to say everybody has to join,” she told ABC News. “So, for that reason, the mandates that Sen. Clinton is talking about, I think are going to be more successful in achieving the goal.”
She added: “I just have more confidence in Sen. Clinton’s policies than Sen. Obama’s on this particular issue.”
Still, she and her husband have stopped short of offering any formal endorsement though some of their former campaign aides also seem to be leaning toward Clinton.
So let’s see if they change their minds and endorse a candidate before the primary. If they do, that could have a real impact.
