Conventions speakers scheduled for Monday

FORMER REP. JIM LEACH: A leading Republican moderate, Leach broke ranks with the GOP and endorsed Obama earlier this month.

NANCY KEENAN: The president of NARAL Pro-Choice America angered some female voters in May by endorsing Obama, even though Clinton was still in the race. Keenan praised Clinton but said the group was endorsing Obama when it became clear he would win the Democratic nomination.

JERRY KELLMAN: The Chicago native hired Obama in the early 1980s as a community organizer for Chicago's Developing Communities Project and is often cited as a mentor to Obama.

TOM BALANOFF: The president of the Illinois Service Employees International Union also burnishes Obama's labor credentials. Balanoff has praised Obama's votes against trade deals such as the Central America Free Trade Agreement.

REG WEAVER: Weaver leads the nation's largest teachers' union, the National Education Association. The teachers' union did not endorse Obama until June, after Obama secured the Democratic nomination. "As long as (Clinton) was a viable candidate in the Democratic nomination process, many of our members felt a passionate need to return the loyalty she has earned over decades of support," Weaver wrote at the time.

RANDI WEINGARTEN: Weingarten is president of the American Federation of Teachers. The 1.4 million-member union endorsed Clinton last October but now backs Obama. Despite support for Obama from both teachers unions, not all educators are happy with Obama, who has spoken in favor of performance-based merit pay for individual public school teachers.

LISA MADIGAN: Illinois' attorney general has at times been mentioned as a candidate to replace Obama in the Senate for the remaining two years of his term if he wins the presidency.

DAN HYNES: Like Madigan, Illinois' comptroller has been mentioned as a possible Obama successor in the Senate. Hynes unsuccessfully challenged Obama for the 2004 Democratic Senate nomination but has since been a major Illinois supporter of Obama's.

ALEXI GIANNOULIAS: The Illinois treasurer was backed by Obama, an endorsement that helped the banking heir win his seat. In return, Giannoulias helped Obama win support among Greek voters in the Chicago area and has raised more than $250,000 for Obama.

MIGUEL DEL VALLE: Chicago's city clerk rounds out Monday's group of Illinois officials talking up the candidate from their home state.
