TROY, Mich. (AP) -- Two more Michigan superdelegates on Monday endorsed Democratic presidential candidate Barack Obama as the Illinois senator talked about the economy to an enthusiastic audience at Troy High School.
Southfield Mayor Brenda Lawrence told the crowd that she was supporting the front-runner. Obama thanked her for her support when he took the stage a short time later.
Michigan Education Association Executive Director Lu Battaglieri told The Associated Press he also is endorsing Obama. That gives Obama seven Michigan superdelegates, tying the number rival Hillary Rodham Clinton has in the state.
A crowd of at least 1,000 people at the high school in Oakland County north of Detroit warmly welcomed Obama's promises to "make sure our economy is working for everybody."
He said Michigan was a great place to create alternative-fueled vehicles and more more into the alternative energy field.
He also promised to do more for education.
"Troy High School is one of the best schools in the country," Obama said. "I want the kids in Detroit to get the same education."
Obama is making his second visit to Michigan in three weeks to introduce himself to voters. He avoided the state for 10 months because Michigan broke Democratic National Committee rules by moving its presidential primary to Jan. 15.
Obama won 59 Michigan delegates Saturday during a raucous DNC rules committee meeting even though he wasn't on the ballot here. Hillary Rodham Clinton will get 69. But each delegate will get only half a vote.
A recent statewide poll shows Obama slightly trailing Republican rival John McCain in Michigan.
