And it's blatantly false. Republicans tend to crash the economy leaving it for Democrats to sort it out.
It may be false in the sense that he won't protect the economy, but that wasn't Gordon's point. He said that support for Trump was based on the
feeling that he would handle the economy better than the democrats. It is about perception rather than reality - and the reality is often based on situations way beyond the control of one administration in one country.
Across the world many incumbent governments (regardless of their economic political positions) are being hit because of the economy, inflation etc etc - but the fact that every country (well pretty well every country) has been hit by inflation post-COVID and post Ukraine etc suggests that these aren't factors influenced by individual government decisions. But the electorates tend not to notice or care - 'our cost of living is through the roof so we need to kick out the government'.
It is likely (let's hope) that global events will stabilise over the next few years (regardless of the actions on individual governments). If so both Trump and Starmer will be able to push the narrative that the country/economy was broken when we came to power and look at it now in 2028/9 - we fixed it.
