Remember that week during Gov. Walker’s primary campaign when he took four different positions on immigration? At least with respect to Donald Trump, Walker has stretched out the process of wavering. Just a few weeks ago, he was backing away from previously supportive comments about Trump and saying he had not made up his mind about endorsing him. Now he says that the pledge Senator Cruz took to support the nominee is sacrosanct and that it was wrong for Cruz to put in a good word for conscience the other night.
If you think something you did might have been wrong, I can see how it would be a relief to see most of your peers doing it too–and galling to see anyone do otherwise.
