The simplest explanation of why Romney is losing.

It's because people still blame George W. Bush and the Republican Party for the mess we're in.

"Since President Barack Obama's first year in office, a majority of Americans have said that former President Bush's policies were more responsible for current economic problems than Obama's policies were. That figure is at 57% today, with 35% saying the current president and Democrats are mostly to blame for economic problems," adds Holland.
