It's possible that, in all of politics, there's no more shameless, unpleasant, and yet ultimately-inconsequential creature than Lindsey Graham. Like a political remora, he'll suck up to whatever candidate he feels will drop enough leftovers to allow him to keep swimming. Previously, he hitched his wagon to the failure known as John McCain. Now, apparently, he'll be stumping for Ted Cruz.
To set the stage, let's remember that Lindsey Graham is a vile worm who - just a few weeks ago - was joking about murdering Cruz on the Senate floor.
