With his wife and children at his side, Obama repeatedly said that America is tired of political infighting and that now it's time for change.

"I think people are tired of bickering and arguing, they want to get to work," Obama said.

I don't remember hearing this exact riff in Pennsylvania.  His multiple mentions of telling people exactly what was going on made me wonder whether Obama was almost morphing into Mr. Straight Talk himself, John McCain.

And Obama even threw in a line about how people want "solutions."

"I believe this country doesn't want to bicker and fight.  They want to roll up their sleeves and solve problems," Obama said in Fort Wayne, Indiana.

That one really made me spit my gum out, because "solving problems" has been all but politically trademarked for months by Hillary Clinton, who has made the point that Obama only gives speeches, while she offers real solutions.

I know this is only stump speech rhetoric, but it tells me that Obama's people have been looking for ways to re-tool and re-energize the candidate on the Campaign Trail. 

Obama seemed on his game one minute, and then he was flubbing his lines the next.  He definitely sounds tired, but that's when you've got to either dig deep, or find a doctor to prescribe some Ibogaine.

As for Hillary, she was her "fighting" self as well during stops in Fort Wayne, South Bend and Indianapolis, arguing that she is the one who can best bring home what Democrats want.

While Obama frequently mentioned Clinton by name - sometimes her last name and sometimes her first name - Clinton has stuck to the "my opponent" thing for a couple weeks now.

"There's a big difference between us," Clinton told a crowd at a small college in Fort Wayne, Indiana.  "And the question is, who understands what you're going through and who can you count on to be on your side?"

Clinton will spend election night here in Indianapolis, which means they think she's got a good chance to win the primary here.

As of midnight Sunday night, Obama had still not made public where he would be on Tuesday night.

Both candidates will make several stops in both Indiana and North Carolina on Monday in a frantic run to the May 6th primaries.
