Didn’t democrats turn a funeral of one of their flock into a political rally awhile back? This is going to blow up in their faces!
Yes - Paul Wellstone, Democrat senator from Minnesota in 2002, before the midterm election. Tom Harkin was particularly obnoxious. Republican congressfolks who showed up to express condolences were booed in the arena. (they didn't speak or eulogize).
It was known thereafter as the "Wellstone Memorial" and may have led to increased Republicans in the House, and a flip of the Senate from D to R. Both houses of Congress remained in Republican hands until the 2006 election, when both houses flipped.
