Conservative talk radio host Rush Limbaugh responded to President Barack Obama's jab at him Friday.

During an interview that aired on CBS' "Early Show," Obama said:

When you listen to Rush Limbaugh or Glenn Beck, it's pretty apparent, but keep in mind that there have been periods in American history where this kind of vitriol comes out...It happens often when you've got an economy that is making people more anxious, and people are feeling that there's a lot of change that needs to take place. But that's not the vast majority of Americans. But that's not the vast majority of Americans.

In an e-mail to conservative columnist Byron York and linked on the talker's website, Limbaugh said that voters are more worried about Obama's agenda than the economy:

I have yet to have a down year at the EIB Network... and most Americans do not believe President Obama is trying to do what's best for the country. Never in my life have I seen a regime like this, governing against the will of the people, purposely. I have never seen the media so supportive of a regime amassing so much power. And I have never known as many people who literally fear for the future of the country
