President Obama says he is "absolutely positive" he has made the right decisions on health care, financial reform and the stimulus bill. "I knew these things might not be popular," he tells Fox News Channel's Bret Baier, but he says he believes that in time he will be "vindicated in having made those tough decisions."http://content.usatoday.com/communities/theoval/post/2010/03/obama-says-he-will-be-vindicated-by-history/1?csp=hf
When a president says he will be vindicated by history, it means the president knows he's getting hugely unpopular now.
P.S. - Unless they're freeing the slaves, they're usually not vindicated by history. Think of Iraq, Vietnam, Carter's economic plan, Ford pardoning Nixon, Watergate, etc.
