Homeowners vote red. Renters vote blue.

Will President Donald Trump’s 50-year mortgage make a red voter out of you?

That is what the president hoped on Saturday, when he posted the idea of stretching out the customary 30-year repayment terms for home mortgages to 50 years.

Turns out, that idea is smoke and mirrors. But at least Trump is recognizing that home affordability is a real crisis, not fake news.

“Affordability” is the campaign pledge that produced big wins on election day, and most winners were Democrats.

Affording a home is increasingly out of reach. The median age of the first-time homebuyer just hit 40 years old, according to the National Association of Realtors. Many women are worried about hitting the brick wall of no longer being able to bear children, and they still can’t afford a starter home.

In 1991, the median age of someone buying their first home was 28, but in the last few years it’s become the impossible dream for people even in their 30s. The implications are huge, not only for starting a family but also for voting.

Renters favor Democrats by almost two to one, according to data from the American National Election Studies. Homeowners are twice as likely as renters to identify as “strongly Republican,” reports Aziz Sunderji, an economist who analyzed several decades of this data.

Starting in the 1970s, renters were slightly more inclined to vote Democratic than Republican, but in the last 20 years, they have swung sharply leftward.

Making homeownership possible is not only good policy. For Republicans, it’s smart politics.

In New York City, people in their 30s who are earning good money — as much as $120,00 or more, according to economics reporter John Carney — cannot make the leap to homeownership. In the mayoral election, strong support for democratic socialist mayor-elect Zohran Mamdani came from Brooklyn neighborhoods inhabited by “downwardly mobile professionals” who are settling for cramped rental apartments and roommates. They have “no hope of buying a home,” Carney reports.

Scalded by the election results last week, Trump floated the idea of a 50-year mortgage on Truth Social, with side-by-side pictures of himself and Franklin Delano Roosevelt, who devised the 30-year mortgage after the Depression to relieve homeowners.

The 50-year mortgage is a nonstarter because it’s prohibited by Dodd-Frank, among other reasons. But there are realistic steps to help first-time buyers get into the market.

Lowering mortgage rates will help. Many current homeowners, especially the elderly, who would like to downsize are locked into their current homes because they’re financed at low rates. If they sell and buy a new property, they’ll be stuck with higher interest rates. So they’re waiting, keeping urgently needed inventory off the market.

Trump has been all over Federal Reserve Chairman Jerome Powell to lower interest rates. He’s already done so twice, in September and October, and some predict another hike in December.
