 As President Obama prepares to deliver his State of the Union address tonight, congressional Republicans are promising to respond with what they call their grumpiest faces ever. House Majority Leader Eric Cantor (R-Virginia) confirmed that the G.O.P. have been practicing in front of mirrors for weeks in the hopes of creating just the right grouchy-face look for the TV cameras. Tonight, President Obama is going to lay out his vision for this country, he said. We owe it to the American people to look like someone just pissed in our cornflakes. For some, the task of looking crabby is just another day at the office, said Senator Mitch McConnell (R-Kentucky), widely viewed by his fellow-Republicans as the reigning sourpuss in Congress. Its a gift I have, he said. Its one of the perks of being a steaming cauldron of spite. Perhaps the most sustained performance of sulkiness will fall to House Speaker John Boehner (R-Ohio), who will be seated behind the President and therefore will be on camera for the entire duration of the address. Theres a lot of pressure on me to look sullen for an entire hour, but Im up to it, he said. It helps that I will be in the same room with so many people I despise.
