During a discussion on the future of newspapers and journalism on the Chris Matthews Show today, Time’s Joe Klein said that “on complicated stories, you can do this stuff on the internet.” Matthews responded by asking “who’s going to fact check?” As CNN’s Gloria Bolger began to answer that online editors would, Matthews interjected, “the bloggers don’t fact check.” “Nobody fact checks” online, added Klein. Watch it:

It’s ironic that a cable news host such as Chris Matthews would attack bloggers for supposedly not checking their facts, considering the amount of falsehoods and factually inaccurate statements he regularly utters on the air — which have all been fact-checked by bloggers.

Over the past several months, the right wing has been advancing the discredited myth that President Obama is not a natural-born U.S. citizen. These so-called “birthers” claim that Obama hasn’t produced his a valid birth certificate to prove that he is eligible to be president. (He has). CNN’s Lou Dobbs is the latest to traffic in this nonsense, despite the fact that his own guest-host debunked the “birther” claims on Dobbs’s show.

Today on MSNBC, host Chris Matthews interviewed Rep. John Campbell (R-CA), co-sponsor of a bill that would require candidates for president in the future to present a copy of his or her birth certificate “to establish that the candidate meets the qualifications” for president. “The proposal is not crazy,” Campbell said in defense of the measure. “Congressman, nice try,” Matthews replied. “What you’re doing is appeasing the nutcases…you’re verifying the paranoia out there,” he said. Matthews then held up a copy of Obama’s birth certificate and said, “That’s the way to deal with this, mail this birth certificate to the wacko wing of your party.”

Matthews asked Campbell seven times if he believes Obama is a natural born U.S. citizen, and after a series of dodges, Matthews said, “You are feeding the wacko wing of your party.” Campbell finally answered, “As far as I know, Yes.” “As far as you know? I’m showing you his birth certificate!” Matthews exclaimed:

MATTHEWS: It’s on the screen now, take a close look. It says “Barack Hussein Obama.” He was born August 4, 1961 in Honolulu, is that a state? Yes it was. His mother was caucasian, his father was African. What more do you want? He’s male. He was born, by the way at 7:20 P.M. in the island of Oahu. What more do you want? I mean, I’m serious, you say “as far as you know?” You are playing to the crazies.

“Was he born in this country?” Matthews asked again. “Yes, I believe so,” Campbell replied. “Ok, finally we’re making progress,” Matthews said. Watch it:

Rep. Mike Castle (R-DE) was barraged by birthers at a local town hall meeting in Delaware recently and was forced to inform the crowd — much to their dismay — that Obama is indeed a natural born citizen.

In their latest attempt to rally against the new economic stimulus package, many conservatives are ridiculing a measure that would aid states by making it easier to provide comprehensive family planning services to low-income women. Rep. Robert Wexler (D-FL) defended the measure on MSNBC’s Hardball this afternoon, noting that “family planning saves, if done correctly, an enormous sum of money down the road in the health care system.” However, host Chris Matthews thought the measure sounded more like something straight out of communist China:

MATTHEWS: I don’t know. It sounds a little like China. [...] I think everybody should have family planning and everybody believes in birth control as a right. I’m for — abortion is a right and all that. It’s all right. But why should the federal government have a policy of reducing the number of births?

Watch it:

What Matthews appears to be referring to is China’s “one-child policy,” a law that prohibits most couples from bearing more than one child. But of course, the House’s stimulus provision does no such thing. Instead, like Wexler noted, it provides funds to help states and low-income working women reduce their health care costs.

Invoking William Ayers and Rev. Jeremiah Wright on MSNBC’s Hardball with Chris Matthews today, former House Majority Leader Tom DeLay declared that Sen. Barack Obama (D-IL) is a “radical” and a “Marxist.” Matthews asked DeLay if he was comfortable with the McCain campaign using phrases like, “socialist, communist, Anti-American.” “Absolutely,” DeLay responded.

Referring to his recent interview with Rep. Michele Bachmann (R-MN), Matthews said, “We had someone on this show the other day who said [Obama] should be checked out for being anti-American. Where would you put him, do you think he’s anti-American?” DeLay said, “I’m not going to go that far,” but boasted, “I tagged him as a Marxist months ago.” Watch it:

DeLay’s remarks come just days after WFTV’s Barbara West quoted Karl Marx before suggesting to Sen. Joe Biden (D-DE) that Obama is a “Marxist.” Earlier this week, when asked if Obama’s policy proposals amounted to communism, McCain said, “I don’t know.” Gov. Sarah Palin (R-AK) has suggested on multiple occasions that Obama is a “socialist.”

Rep. Steve King (R-IA) claimed over the weekend that Obama’s policy proposals would transform the country into “totalitarian dictatorship.”

In an April 13 New York Times magazine profile of MSNBC host Chris Matthews, Mark Leibovich noted that “sometimes during the commercial breaks” of MSNBC’s presidential primary coverage “Matthews will boast to” his colleague and fellow MSNBC host Keith Olbermann “of having restrained himself during the prior segment.” “And I reward him with a grape,” Olbermann said snarkily. During last night’s primary coverage, when Matthews started to get a little worked up, Olbermann offered a grape. “No, I’ve had enough grapes buddy,” Matthews replied. Watch it:

In the Times profile, Olbermann told Leibovich: “There is a sense at times that we are always joining Chris Matthews already in progress…and he has no idea when it stops and starts. My responsibility sometimes is to grab the wheel when he doesn’t hold it.”

On MSNBC’s Hardball last night, while discussing Sen. Barack Obama’s (D-IL) recent campaign stop at a Pennsylvania bowling alley, host Chris Matthews broadly generalized about African-Americans when he said to MSNBC political analyst Michelle Bernard, “You know, Michelle — and this gets very ethnic, but the fact that he’s good at basketball doesn’t surprise anybody.” “But the fact that he’s that terrible at bowling does make you wonder,” added Matthews. Later, Matthews said Obama’s bowling “form” wasn’t “the most macho.” Watch it:

Also on MSNBC earlier in the day, Joe Scarborough called Obama’s bowling performance both “dainty” and “prissy.”

On this evening’s Hardball, Chris Matthews made this incredulous and puzzling statement:

Some people think [the Republican presidential race] has come down to McCain, Romney, and — just because Giuliani hasn’t been beaten yet — Giuliani.

Watch it:

Note to Chris: Giuliani has not only been beaten, he’s been crushed. To recap: Giuliani finished fifth in Iowa with 4 percent, fourth in New Hampshire with 9 percent, sixth in Michigan with 3 percent, sixth in Nevada with 4 percent and sixth in South Carolina with 2 percent.

UPDATE: Tim Grieve has more.
