evidence: The Democrat Walz, at times stumbling over his words, laid out his defense for Harris’ housing plan, which includes tax incentives to spur more home construction and a $25,000 federal down payment credit for first-time buyers. He also repeatedly took aim at investor homebuyers, blaming them for driving up the cost of housing. [...] At one point, CBS News co-moderator Margaret Brennan pressed Walz for details on Harris’ plan to spur construction of 3 million new homes and subsidize down payments, asking: "Where are you building these new homes, and won’t handing out that kind of money just drive up prices higher?" [...] "We don’t want to blame immigrants for higher housing prices. But we do want to blame Kamala Harris for letting in millions of illegal aliens into this country, which does drive up costs," said Vance. "Twenty-five million illegal aliens competing with Americans for scarce homes is one of the most significant drivers of home prices in the country. It’s why we have massive increases in home prices that have happened right alongside massive increases in illegal alien, alien populations under Kamala Harris’ leadership."
