The release of Romney's tax returns has sparked a lot of debate over his absurdly low tax rate and whether this revelation will harm his campaign for the presidency. Rupert Murdoch, for one, thinks that it could. The News Corp. owner tweeted Wednesday, "Romney's tax returns might kill his chances. See Republican establishment panic now!" The Wall Street Journal, a Murdoch paper, urged the presidential hopeful to take advantage of the attention on his taxes to push for tax reform.
