The prevailing theory is that no Republicans were in Selma this weekend to celebrate the 50th Anniversary of the Selma march that provided a pivotal moment in the Civil Rights movement.
One quick look at various GOP leaders' Twitter streams and that notion is fairly easily dispelled. Sens. Tim Scott, Jeff Sessions, and Susan Collins were all there, as well as Rep. Kevin McCarthy, RNC chair Reince Priebus, and a number of others, including former President George W. Bush, who walked on the front lines and was given a place of honor on stage during the speeches.
Of course, George W. Bush doesn't have the kind of over-active Twitter feed to demonstrate his commitment to civil rights on, and if you were paying attention to basically any dispatch from the Selma event, you'd never even know he was there. The New York Times, for starters, cropped him and his wife Laura right out of the photo they put on their front page.
