Rankings released by YouGov/Economist show that Ronald Reagan is viewed as the greatest president of the last 100 years, while Obama is viewed as the "biggest failure."

The poll asked respondents "to rate each president [since Theodore Roosevelt] in six categories: great, near great, average, below average, failure, and don't know."

Results showed that Reagan bested Franklin D. Roosevelt (FDR) and John F. Kennedy (JFK) in a tight race for the top spot. 32 percent of the respondents categorized Reagan as "great," while 31 percent labeled FDR "great" and 30 percent chose JFK.

When it came to ranking presidents viewed to be a "failure," Jimmy Carter and Richard Nixon fared better than Obama.

Of those polled, 22 percent of respondents rated Carter a "failure," while 30 percent gave that same ranking to Nixon. But Obama took first place at the bottom of the list, with 37 percent of respondents choosing him as the biggest "failure" of all.
