Rush Limbaugh is at it again, this time with his glaringly offensive - and tasteless - reference to Senator Kennedy's health. I'm sure you've seen the comment:  "Before it's all over, it'll be called the Ted Kennedy memorial health care bill."  Well, Politico's just up with this post about the deafening silence so far from the GOP's top leaders:  House Minority Leader John Boehner, Senate Majority Leader Mitch McConnell, and RNC Chair Michael Steele: http://www.politico.com/blogs/glennthrush/0309/GOP_silent_on_Rushs_Kennedy_slap.html?showall  Wonder when -- or, more likely,  if -- we'll ever hear anything from these folks?
