“As I’ve traveled around the country I think the wind is at our back. I’ve been to 32 different states. People do want a change,” he told in the crowd in a voice made raw by dozens of stump speeches.

The day before the Michigan visit, Paul had spent the day campaigning in Kansas for Sen. Pat Roberts (R-Kan.), who’s locked in a tough reelection fight.

He plans to visit Pennsylvania on Friday before spending the weekend and early next week in Kentucky campaigning with the embattled incumbent who has needed his help the most: Senate Republican Leader Mitch McConnell (R-Ky.).

The midterm push has allowed Paul to barnstorm the country, making connections along the way that could serve as a springboard to a presidential run in 2016.
