First off, I'll start by saying I'm not an economics expert by any means. I honestly don't know what the results of going back to the gold standard would mean, though majority opinion appears to be that it's basically crazy and would be a terrible financial decision, and only Ron Paul appears to be in favor of it.
Hopefully this isn't ASB, but instead of getting financial advisers that were in favor of what is dubbed "Reaganomics" today ("trickle down effect", etc.), what if Reagan (or another Republican candidate in 1980 who could win the nomination, it's not important) gets a financial advisor who advocates a return to the gold standard in the campaign against Jimmy Carter? Assuming that whoever proposes this manages to still beat Carter, even if its by a tiny amount in the electoral college, what does the economy look like from 1981 to 1985? Presumably it's bad, but it was bad in OTL, too. Assume, however, that the rest of OTL Reaganomics, including its tax cuts, is not put into effect. What happens? Is it possible for the candidate to win reelection in 1985? Is America still on the gold standard today?
