Thursday in politics: Ryan in Ohio for another day, and more

Compared to the past week, Thursday looks to be slow on the politics front. That could change in an instant. Even one word can make a difference. The word "chains" proved that earlier this week.

Rep Paul Ryan will spend much of the day in Ohio. He has a breakfast in Cleveland and a rally in North Canton. He'll end the day at a fundraiser in Richmond, Va. The word to listen for as Ryan campaigns: Medicare.

President Barack Obama, who ended a three-day bus tour in Iowa on Wednesday, and Vice President Joe Biden, who wrapped up a two-day swing in Virginia on the same day, will be in Washington. They are scheduled to meet with Secretary of State Hillary Clinton and Secretary of the Treasury Tim Geithner and also have lunch together. (Wonder if the word "chains" will come up?)

Also worth noting Thursday: Louisiana Gov. Bobby Jindal will campaign in Virginia for Mitt Romney, and Sen. Marco Rubio will do the same in Nevada.

Romney has no public events scheduled Thursday, but he does have fundraisers in South Carolina and Boston.

And then there is this: What's up with Donald Trump? He won't say what his role will be at the Republican National Convention, but he does say it's going to be "pretty wild."
