As someone who watched it, the whole thing...99% of it was just a service...I believe it was his son, who just lost his Father and Mother..gave a very emotional, and if you watched it...you could clearly see...very emotional and also one that was not exactly...one someone of clear thought but of one overcome with grief. Of course taken out of context of that it was not something planned by anyone but his son...it was attacked by the Republican party as if it was some planned DNC speech. Hours of a service where ignored...and they focused on the bits that where more political. And they attacked all out over it for every day till the election...By watching them talk after you would think it was a 3 hour rally...not a funeral that happen to have a few political references as one would expect...and the son of the dead going a bit overboard...and we don't even know if he planned to say any of it, or just overcome with emotion did...But they spun the Funeral to fit them....
A lot of my freinds who where very much Democrats...where having a hard time dealing with his death even weeks later...so I can only imagine what it must have been like for his son. I had a lot of respect for him, even though I never voted for him..and voted for Dean Berkley in that election ( IP party) ....( who as a side not I was actually suppose to interview for a project I was working out, but he had to fly to DC to be sworn in to fill Welstones seat..the day i was to interview him...showing how fast things happened)
I sat at home with my mom dad and sister, and a few freind who where big supports and there mom and dad, also big supporters....we watched it all..to us it was a sad remembrance of a great person...none of us watched feeling it was any type of rally...last I checked rallys should not have people crying most of the time.
Point is, if you inject political themes and motives into the memorial service, then you have opening it up as such, and should not be surprised when your opposition responds in a political fashion.
