Less than three months before the election Republican governor Scott Walker is back on the campaign trail traveling across the state by bus. Walker says recent polls showing him trailing a leading Democratic challenger should be a wake-up call for Republicans. “I think its going to be very, very competitive,” Walker told AM 1170 WFDL’s Between the Lines program. “I’ve said for almost a year that my concern was complacency. The reality is that, largely because of things at the national level, there’s a huge amount of momentum on the other side. Some call it a “Blue Wave” we’ll see if that happens here in Wisconsin.” Walker says the key in November will be turnout. Walker says Republican policies have had a big impact on the state’s record low unemployment rate and generally strong economy.
