Protesters heckle Tammy Baldwin on Syria by singing “Which side are you on?” at the Fighting Bob Fest.

Internal divisions on the left.

U.S. Sen. Tammy Baldwin, D-Wis., ... who opposed strikes in Kosovo, Iraq and Libya -- said she would continue asking President Barack Obama’s administration “tough questions” to further the debate. 

She wouldn't say how she would vote.

ADDED: It looked like this:

"Ron Johnson, Tammy Baldwin: No pair of senators are further apart."

"Johnson, a Republican, ranks to the right of roughly 95% of his Senate colleagues in two well-established nonpartisan rating systems.... Baldwin, a Democrat, ranked to the left of the vast majority of her House colleagues in the same rating systems before she arrived in the Senate last month."

From Wisconsin.    

To use the old travel-guide cliché: a land of contrasts.
