Former president Bill Clinton said in an interview broadcast Sunday that there are "way too many" caucuses in the presidential nominating process.

"I still think we have way too many caucuses," Clinton said on ABC's "This Week With George Stephanopoulos." "They're not democratic. And unlike primaries, they have no legal enforcement. You can break the rules, nobody's gonna say anything. I think there are way too many of them."

Reflecting on the 2008 presidential campaign of his wife, former secretary of state Hillary Clinton, the ex-president said that he learned two main lessons.

"You've got to have a plan for the future that relates to the people. You know, this is not about the candidates as much as about having a plan for the future," said Clinton. "And secondly, you have to have a strategy for presenting your true self to the voters in an environment where there are unprecedented opportunities for those who don't want you to win to paint a different picture of your true self."

Hillary Clinton is a potential 2016 White House contender. Clinton didn't offer any new insight about whether or not his wife will run.

"The next one will be better. It'll be different. Whether she's in it or not, they're all different," Clinton said of the next election.
