Question: What Presidential election did one of the candidates promote a tax policy that advocated for the gold standard?
Context: Samuel Joseph Wurzelbacher ( ; born December 3, 1973), known as Joe the Plumber, is an American conservative activist and commentator.  He gained national attention during the 2008 U.S. presidential election when, during a videotaped campaign stop in Ohio by then Democratic nominee Senator Barack Obama, Wurzelbacher asked Obama about his small business tax policy.  Obama's response included the statement, "when you spread the wealth around, it's good for everybody."  Obama's response was seized upon by conservative media, and by Obama's rival, Republican nominee Senator John McCain, as an indication that Obama was interested in the redistribution of wealth and had a socialist view of the economy.  Wurzelbacher is a member of the Republican Party.
