Massachusetts state Sen. Katherine Clark (D) will soon be the newest member of Congress, after she won a special election Tuesday.

Clark easily won the race for Sen. Edward J. Markey's (D-Mass.) old House seat. Markey won a special election for the Senate seat formerly held by Secretary of State John F. Kerry.

With 88 percent of precincts reporting, Clark led Republican Frank Addivinola 68 percent to 30 percent.

Her victory Tuesday was a foregone conclusion in the heavily Democratic 5th district. She won a very competitive race for the Democrats nomination two months ago.

Clark becomes the third woman to be elected to Congress from Massachusetts in the last five years -- after there had been only three in the previous 200-plus years of the state's existence.
