Madison - The head of the Republican National Committee believes Wisconsin and other battleground states should change the way they allocate their Electoral College votes, but he said he is not inserting himself into how states decide to proceed. "It's not my decision that can come from the RNC, that's for sure," said Reince Priebus, the RNC's chairman. Gov. Scott Walker recently said he was intrigued by the notion of Wisconsin divvying up its electoral votes by congressional district, but that he had not made up his mind on whether to back the idea. If such a system had been in place in November, President Barack Obama and Republican Mitt Romney would have evenly split Wisconsin's 10 electoral votes, rather than having all of them go to Obama. As Republicans have mulled over Romney's defeat, some have promoted the idea of having states such as Wisconsin, Michigan and Ohio give two electoral votes each to the statewide winner and dole out the rest to the winner of each congressional district. Pennsylvania lawmakers failed to pass such a plan in 2011, but a GOP leader there is now pursuing a variation on the theme that would allocate the electoral votes in a way that was proportional to the number of ballots cast for each candidate.
