9/6/12 – Wisconsin delegates helped cap off a raucous roll call of states, as Democrats nominated Barack Obama for a second four-year term as president. The roll call didn’t end until early this morning at the party’s national convention in Charlotte. It officially set up a showdown in November with Republican challenger Mitt Romney. Obama’s name was the only one on the Democrats’ ballot, and Ohio put him over the top. Tonight, delegates are expected to nominate Joe Biden for a second term as vice president. And they’ll hear from Obama and a number of other key Democrats – including Madison Congresswoman Tammy Baldwin, who’s scheduled to deliver a prime-time speech. Baldwin is running against former Governor Tommy Thompson for the state’s U-S Senate seat that’s being given up by the retiring Herb Kohl.
