On the one hand, I'm pumped about Scott Walker "finally" joining the presidential race - as absurd as that sounds 16 months before the election. On the other hand, I'm already rolling my eyes at what he will now have to go through. Walker will want to talk about his track record of taking on entrenched liberals in crucial battles in Madison - and beating them. Consistently. And he'll want to talk about how he would apply those same approaches to governing the nation - which issues he would choose, why he could emphasis them, how he would succeed in Washington as he has in Madison.
