Self-fulfilling prophecy.

(Fox News) — American voters are sharply divided over how things went this year, and they continue to give President Obama mixed reviews. Meanwhile, voters are almost twice as likely to say Obama will be one of the country’s “worst” presidents as to say he will be one of the “greatest,” according to a year-end Fox News poll released Thursday.

Twenty-three percent of voters think Obama will rate as “one of the country’s worst presidents,” up from 15 percent in 2010 and 6 percent in 2008.

Twenty-nine percent expect his presidency will be “good,” 19 percent say “average” and 14 percent say “below average.”

Nearly one in four Democrats thinks Obama will be one of the greatest presidents (23 percent). Twice as many Republicans expect he will rate as one of the worst presidents (46 percent).

And while the number of Democrats believing Obama will be one of the greatest presidents is up from a low of 9 percent in 2010, it’s down from a high of 30 percent who thought that when he was first elected.
