Mitt Romney could have ran for President as someone who had been a moderate Republican Governor of a solid blue state, but he veered hard right to win the primary. That decision came with consequences. Romney was doomed by actions like turning his back on RomneyCare, failing to realize that many voters didn't give a rat's behind about top marginal tax rates, and neglecting concerns of young voters such as student debt.
That's where Romney failed, and it's why no social media overhaul can compensate for policies that fail to address the basic needs and desires of the American electorate.
It's still not 1980 anymore.
