First, you're reading too much into that second to last paragraph.  When I used the word "luckily" it was in the context of the Delaware race only.  I would love nothing more than for the GOP to take the majority.  I was merely stating that it's lucky for us that Delaware didn't put us in jeopardy of losing the chance for that majority.

Luckily, it does not appear that Republicans were going to take control of the Senate anyway, but if the Delaware race does end up costing them the majority, those who backed O'Donnell in the primary "on principle" will be responsible for allowing the Democrats to stay in control.
