Democratic strategist Hilary Rosen issued an apology to Ann Romney Thursday for saying Romney never worked a day in her life, a comment that drew sharp criticism from both sides of the aisle.

Hilary Rosen is hardly the first Democrat to get into trouble for saying the wrong thing. Here are five Democrats who have made some idiotic gaffes.

Joe Biden

You know, I'm embarrassed. Do you know the website number? I should have it in front of me and I don't. I'm actually embarrassed.

We would break the Internet if we listed all of Biden's gaffes. But we'll go with this one, which the vice president made in February 2009 on the Early Show on CBS. Biden was referring to a government-run website that tracks stimulus spending when he forgot the web address, according to politicalhumor.about.com.

Barack Obama

It is just wonderful to be back in Oregon and over the last 15 months we've traveled to every corner of the United States. I've now been in 57 states. I think one left to go.

Check out Obama's gaffe here. Was it jet lag? Whatever the excuse, there really is no valid one.

John Hickenlooper

Now I get to introduce that rising sex star - symbol. I mean symbol - not star.

This is how the Colorado governor introduced his deputy, Lt. Gov. Joe Garcia, according to ABC News. Even with the clarification, it's hard to say exactly what Hickenlooper meant. Rising star? Rock star? We'll never really know.

Bill Clinton

I'm thrilled to be in Macedonia.

Problem is, Clinton was actually in Montenegro when he delivered this gaffe.

John Kerry

Somebody told me the other day that the Secret Service has orders that if George [H.W.] Bush is shot, they're to shoot [Vice President Dan] Quayle. ... There isn't any press here, is there?

Kerry reportedly told this one in 1988 at a business breakfast shortly after George H.W. Bush was elected president. Kerry later issued an apology for the remark.
