The equally obnoxious Jonathan Alter takes it a step further and says it’s “like talking about watermelon or, you know, for Jews, talking about Jews are greedy.”

CHRIS MATTHEWS: The blatantness of this thing, I think, went through the roof the other day when Sarah Palin, about whom people have mixed views put out a Facebook post entitled “Obama’s shuck and jive ends with Benghazi lies” regarding to the Obama administration’s handling of the attack on the Libyan embassy. You know, a dog whistle is a dog whistle, Clarence. A trumpet call is another. Shuck and jive has a particular ethnic connection, not necessarily bad in all cases, it’s sort of slang. It doesn’t mean evil but to throw it at the president as an ethnic shot is pretty blatant.

JONATHAN ALTER: Chris, I actually think my old friend Clarence is being a little bit polite. I think this is rank racism. You know, sometimes people on the right get very upset when people on the left charge racism, but, you know, shuck and jive, that’s like talking about watermelon or, you know, for Jews, talking about Jews are greedy or the Irish are drunk, whatever. These are racist tropes and we need to call them what they are, and I actually think at least implicitly Trump was playing on racism today with his ridiculous stunt demanding Obama’s college transcripts.

Via Newsbusters who note Tingles himself has used the exact same phrase before:

On July 7, 2010, Matthews, while talking to Rachel Maddow and her visit to Afghanistan, wondered, “What has it been like, as you shuck and jive, hang out with the men over there, the women over there, in uniform risking their lives every day?” The late Tim Russert also used the term on July 18, 2003.
