No one vetted Mitt [View all]
How did the Republican Party miss so many of Mitt's problems? You can thank his weak primary opponents.
Remember that Romneys most visible opponents during most of the nomination process were either dramatically underfunded or were otherwise unable to run a normal campaign with a fully staffed opposition research operation and the ability to effectively challenge Romney with what they learned. Rick Santorums campaign was almost comically understaffed; Herman Cain, Michele Bachmann and Newt Gingrich werent much better. Gingrich did benefit from outside attacks, but apparently didnt have the staff necessary (or perhaps the interest in deploying staff) to really know what in the ads was accurate and what wasnt, making it fairly easy for Romney to dismiss the whole thing once some questionable assertions were found. At any rate, most Republican opinion leaders didnt really want to hear that sort of attack in the first place, and so even a lot of anti-Romney Republicans didnt follow up on it.
