Fred Barnes writes in The Weekly Standard that there are four fears people have about President Obama which, though they might not be justified, are not unreasonable:
Barack Obama is the apostle of hope. But he also arouses the flipside of hope--fear. And while the fear he stirs may turn out to be unfounded, it's not irrational. People don't know who Obama really is or where his ideological center of gravity rests, to the extent it rests anywhere. He was a liberal in the Senate and the campaign, a centrist in the transition, and who knows what he'll be as president. He's elusive.
I count four separate fears. Whether he's a crypto-Marxist is not one of them. Neither is the absurd fear that he's secretly a Muslim, even a closet jihadist. Nor is the groundless claim Obama was actually born outside the United States and isn't really an American citizen. Forget all those. They're nonstarters.
Barnes goes on to discuss the fear that Obama doesn't know what he's talking about, is too much of a pushover, will be too much like Jimmy Carter on foreign policy, and lacks the resolve necessary to make unpopular decisions. Read the article to understand Barnes' reasoning for each of these. It's pretty good.
