MSNBC's supposedly conservative host Joe Scarborough on Tuesday continued his months-long attack on the Republican presidential candidates.

After telling his Morning Joe viewers that he would consider voting for potential third party candidate Ron Paul if Newt Gingrich won the nomination, Scarborough said he could "in five minutes write a list of 200 Republican members of the House of Representatives" more qualified than "the presidential candidates that are running right now" (video follows with transcript and commentary):

The GOP presidential candidates, at the upcoming ABC News debate in Iowa, should brace themselves to be splattered with tough questions from the left from moderator George Stephanopoulos. The good news for them is that most should be well-prepared for the left-leaning sliders, as many have already been subjected to Stephanopoulos’s liberal questioning on Good Morning America. In 20 interview segments this year with the GOP candidates, totaling nearly two hours (110 minutes), an MRC review has documented Stephanopoulos has consistently pressed his guests from the left. Of questions with an ideological bent 75 percent (36) were from the left with just 25 percent (12) of them coming from the right.  

When current GOP frontrunner Newt Gingrich showed up on the January 18 edition of Good Morning America, Stephanopoulos prodded the former Speaker of the House if he was prepared to put 129 million Americans at “risk” with his opposition to Obamacare. (video after the jump)

CBS's Jan Crawford played up Newt Gingrich's "baggage" on Friday's Early Show, underlining how the Republican presidential candidate is "going to be hit hard for his ties to corporate interests, the ethics allegations...even his personal relationships- his adulterous affairs." Crawford also spotlighted the claim that only Herman Cain's "die-hard supporters...think that he can stay in this race."

The correspondent first reported on the allegation that Cain had a 13-year affair with Ginger White and how the candidate recently admitted to helping White financially. Crawford shifted to Gingrich by stating that "in a crowded field, that could help candidates like Newt Gingrich, who continues to surge ahead." She then used her "baggage" term, and highlighted a "scathing new ad" from GOP competitor Ron Paul, which targeted Newt.

Jon Stewart, on Thursday's Daily Show, repeatedly mocked Rick Perry for his, as he put it, "brain turd" moment at this week's CNBC debate. However, Perry wasn't the only GOP candidate Stewart made fun of. Everyone from Perry to Santorum took a hit. The only candidate Stewart didn't mock was Mitt Romney, whom the Daily Show host declared to be the winner of the whole race. "It's over! Indecision 2012 Mercy Rule Edition. Because in presidential primaries, as in little league, if one team is up 10-0 in the third you call it a day an you head over to Friendly's for some Fribbles and some food poisoning."
                                             
Stewart initially teased his audience with the Perry clip by calling it: "Rick Perry's now infamous ABC Wide World of Sports agony-of-defeat-worthy brain turd." Then he went on to savage the other GOP contenders on his November 10 show. (video after the jump)

Hours before Republican presidential candidates faced off in Tuesday's debate in Las Vegas, Martin Bashir took a swipe at six of them.

On the MSNBC program bearing his name, the host said that since Mitt Romney is "the inevitable candidate," the rest of the contestants are auditioning "for future employment" at Fox News (video follows with transcript and commentary):
