Michelle Obama attends Chicago event
CHICAGO Michelle Obama's obviously feeling pretty good Friday, too, as she talked about the impact of the presidential campaign on her family at Congressman Jan Schakowsky's annual power lunch and fundraiser at McCormick Place.
"My family is doing great. I am particularly proud of my husband. The only two people I am more proud of than him are my daughters. They have just been amazing little troupers through all of this," said Michelle Obama.
Barack Obama talked about John McCain, not Hillary Clinton Friday as he campaigned in Oregon, 2,000 miles away.
"Senator McCain is running for president to double down on George Bush's failed economic policies," said Barack Obama.
But the Democratic frontrunner says it is premature to talk about running mates because he hasn't won the nomination yet.
"Until I'm the nominee, I don't want to speculate on running mates. I will say that she has shown herself to be an extraordinary candidate," he said.
Clinton campaigned in Oregon and South Dakota Friday. And it's clear from the tone of her latest TV ad that she's not conceding anything yet.
"Standing up for people who weren't getting a fair shake, that's been the purpose of my life, and it will be the purpose of my presidency," the ad says.
But even Illinois' only uncommitted super delegate, Chicago Congressman Rahm Emanuael, is talking like the race is over.
"At this point, Barack is the presumptive nominee, at this point," he said.
"I do respect and like Hillary Clinton very much. Now the decision she has is how to exit in a way that all of us can-- that her legacy will be very, very important, and her future will be very, very bright," said Schakowsky.
