Bad economy, more money raised these past few months, and incumbent in the mid 40s in terms of approval ratings and you still trail by five in GOP-leaning poll.
Mitt Romney flat-out sucks as a candidate.
No, really? OF COURSE!!!!!!! We needed someone like Palin or Bachmann who would have been able to appeal to a vast swath of the electorate. We didn't need Osama-lite.
No, Christine O'Donnell would have been best. Plus she would have the Wiccan vote all locked up.
The Republicans really needed a RINO to defeat President Obama -- someone able to avoid offending the secularist voters of Northern states. The Mitt Romney of the 1990s would have fit the bill. Instead he approached the lunatic fringe and can't win the center. But the GOP has effectively purged the moderates.
Barack Obama won by 7% in 2008, and this 5% gap appears before the unions begin their GOTV drives and the Obama campaign apparatus comes out of mothballs.
