Tammy Duckworth To Run For Congress In Illinois, Will Face Raja Krishnamoorthi In Primary

CHICAGO -- Iraq War veteran and former Assistant Secretary of Veterans Affairs Tammy Duckworth says she's running for Congress.

The Democrat announced Wednesday that she'll file paperwork to run in the newly drawn 8th Congressional District in Chicago's western suburbs. The district has no incumbent.

Spokesman Pete Giangreco says the 37-year-old will file the paperwork with the Federal Election Commission on Wednesday or Thursday.

Duckworth lost both her legs in a rocket-propelled grenade attack while serving in Iraq. She ran unsuccessfully for Congress in 2006 in another district. Parts of that old district are included in the new 8th District and are areas Giangreco says she won last time.

Another Democrat, Raja Krishnamoorthi (krish-nah-MOOR'-thee), is also running for the nomination in the new 8th District. He has busied himself in the month since announcing his candidacy laying the foundations of a campaign and earning the support of a number of local power-brokers, including Cook County Board President Toni Preckwinkle and many other county-level Democrats.

Krishnamoorthi also has relatively wide name recognition after a bid for comptroller in 2010, which he narrowly lost in the primary to David Miller. Miller would go on to lose to Republican Judy Baar Topinka.

The 8th District has an Asian-American population of upwards of 12 percent, which Krishnamoorthi has said is "one of the highest concentrations of Asians in the entire Midwest." Both he and Duckworth, who was born in Thailand, have Asian backgrounds.

So far, no Republican candidate has formally announced candidacy. The district leans significantly to the left, earning a roughly D+7 rating on the Cook partisan voter index.
