Third-party presidential contender Robert F. Kennedy Jr. pointed to housing affordability as he made his case to Southern California voters ahead of the November election.

“If we’re going to keep our middle class — which is the greatest economic engine in the history of mankind — if it’s going to continue to be the foundation stone of democracy, we need to make sure that all of our kids can get into houses,” said Kennedy.

Kennedy, 70, has qualified to be on the ballot in California, Delaware, Hawaii, Michigan, Oklahoma and Utah so far, per the New York Times’ tracker. Petitioning for ballot access is ongoing in several other states, according to his campaign.
