After Rick Santorum crushed the opposition in Saturday's Kansas caucuses, Twitter lit up with "Wizard of Oz" references, most of them predictably lame. A selection: "Rick Santorum wins Kansas. In related news, Dorothy no longer wants to go home." "Looks like Dorothy better buy some aspirin." "The Wizard wore a sweater vest." "Tin Man takes second." "Clearly Romney needs a heart, a brain and some courage." "Exit polling showed the dog-on-the-roof episode cost Romney the Toto vote too." Slate political writer Dave Weigel tweeted, "Exclusive photo of Mitt Romney's Kansas caucus director" with a photo of the Wicked Witch of the East's ruby-slippered feet beneath Dorothy's house. At least Seth Meyers went another way in his "Weekend Update" segment on "Saturday Night Live": "Santorum was expected to do well in Kansas, because it's also a giant square."
