It will be the battle of the bands between Michele Bachmann and Tim Pawlenty at the GOP straw poll in Ames Aug. 13. The former Minnesota governor announced his music lineup today: The Nashville Christian worship band SONICFLOOd and local Iowa favorite The Nadas. Bachmann has lined up country music legend Randy Travis (and others). The Ames straw poll has far-reaching implications in presidential politics. But, at bottom, it's a fundraiser. So, ah, inducements to vote are allowed. Most campaigns offer to cover the $30 ticket. On top of that, Bachmann's tent offers a petting zoo, service dogs and funnel cakes. Pawlenty is offering up Famous Dave's BBQ and Dairy Queen Blizzards. We report, you decide.
