By CNN's Jack Cafferty:

What a difference four years makes.

When Barack Obama ran for president against Hillary Clinton and John McCain in 2008, he was unstoppable.

He generated the kind of excitement and enthusiasm among voters that is rarely seen in politics. People couldn't get enough of him and his messages of hope, change and "yes, we can."

Four years later, a lot of that optimism and excitement are gone.

"How the mighty have fallen" is how Maureen Dowd describes it in her New York Times column headlined "Dreaming of a Superhero." 

"The president who started off with such dazzle now seems incapable of stimulating either the economy or the voters,” she wrote.
The economy remains weak. Friday's dismal jobs report triggered a selloff, and the stock market has now erased all its gains for the year.

As for the voters, a lot of them are disgruntled – including many in the president's own base.

A Forbes column describes how Obama is being left behind by the left wing of his party.

They're frustrated that the president hasn't followed through on key promises like closing Guantanamo Bay, ending the war in Afghanistan or getting tough on Wall Street.

There are anti-Obama e-mails coming from the left that describe a "psychopathic megalomaniac" in the White House and "a cancer in the presidency" – and these are liberals.

Part of this is due to the ugly reality of governing. But you can even see it in the president's campaign events.

There were more than 4,000 empty seats in an Ohio arena that seats 18,000 when the president officially launched his re-election campaign.

That wouldn't have happened four years ago.

Here’s my question to you: When it comes to President Obama, what happened to the magic of 2008?
