Tip O'Neill famously said "All politics is local."
Each of the congressional races will boil down to how people are feeling in any given state or district...but when you step back and look at the whole map...national trends do emerge: Voter anger, people who are fed up with business as usual in Washington, and outsiders with lots of money to spend trying to unseat career politicians.
All of those roll into one in the Connecticut Senate Race...which we're profiling tonight on the CBS Evening News.
Just three months ago, Attorney General Richard Blumenthal was cruising to victory. Today, challenger Linda McMahon, the former WWE CEO...is just six points behind....and right now, President Obama is in Connecticut...stumping to save a seat that has moved well out of the safety zone.
It's just one of the 37 Senate seats on the line...but when the big picture means control of Congress...well politics aren't looking so local any longer.
That's a page from my notebook.
