a tight race between Ms. Coakley and her republican challenger, state Sen. Scott Brown:

Abou Scott brown-

Scott Philip Brown (b. September 12, 1959)is a Republican Massachusetts State senator representing the Norfolk, Bristol & Middlesex District since 2004.He is the Republican candidate to fill the U.S. Senate seat vacated by the death of Ted Kennedy in the upcoming 2010 U.S. Senate special election. While initially trailing Martha Coakley (the current Attorney General of the Commonwealth of Massachusetts) in polling by large numbers, the Republican closed the gap in January 2010, running even or ahead of Coakley in recent independent and internal polling.

Brown is a graduate of Wakefield High School (1977), Tufts University (1981), and Boston College Law School (1985). He is a practicing attorney specializing in family law

A poll released late Thursday shows Coakley has fallen behind Mr. Brown by four percentage points. Much of Mr. Obama’s agenda depends on Democrats’ filibuster-proof 60-vote majority in the Senate.

“This is not about healthcare. Any bill except the federal budget can be filibustered,” Mr. Clinton proclaimed, after touting Coakley’s positions for financial and healthcare reform.

About Martha Coakley-

Massachusetts’ Senate race has received national attention because Coakley has promised to vote for the healthcare reform bill while Brown has promised to vote against it. That means the fate of the bill effectively rests with Massachusetts voters Tuesday.
