Politico: Wisconsin Gov. Scott Walker took a hard line Monday against any compromise to break the stalemate over union bargaining rights here - a sign of just how dug in both sides are ahead of a lopsided legislative session Tuesday that will be marked by the continued absence of all Democratic lawmakers. Protesters flooded the Capitol for the eighth day Monday to mark their opposition to Walker's call to strip collective bargaining rights from public-sector unions to close the state's budget gap, a fight that has drawn the attention of activists from the left and the right.
