CEDAR RAPIDS, Iowa (AP) – While Hillary Clinton has been rallying Democrats out West, former President Bill Clinton has been carrying her campaign’s message through Iowa.

Next week, when the Democratic front-runner returns to Iowa herself, her daughter, Chelsea, will be courting supporters in New Hampshire.

The family tag-team across the early voting states is just a glimpse at the stable of surrogates on standby to help elect another Democrat to the White House in November.

President Barack Obama has already pledged to be an active participant in the general election. Vice President Joe Biden has made clear he wants to play a role. And popular first lady Michelle Obama is likely to get involved to protect her husband’s legacy.

It’s a weighty group of Democratic stars that Republicans acknowledge they can’t match.
