In a state where Democrats outnumber Republicans by 3-to-1, a victory by Scott Brown could send a very clear message...all the change Americans heard about a year ago may not be something they still believe in.
A Brown victory over Martha Coakley puts health care reform in serious jeopardy...Democrats will no longer have the 60 votes they need to move forward.
It's also a sign that the so-called Tea Party movement is not all talk. The GOP has capitalized its momentum by tapping into frustration about a mounting deficit, taxes and big business bailouts. Some say this vote is a referendum on the President's agenda overall.
This year, by just letting a tea kettle simmer, Republicans may have picked up some steam.
That's a page from my notebook.
