The problem is ARROGANCE. Why build it now, in the middle of a campaign season? This is no different than President Obama taking vacation after vacation, often with huge numbers of travelers, and essentially telling the public that they can stuff it, if they don't approve.
If Mitt wants to build (or upgrade) a house in a still-nice area of California, how about waiting until AFTER THE ELECTION, when it won't be fodder for Obama and his bunch (assuming he gets the nomination)? Does he REALLY think he's got this all sowed up, already?
I could go on about how former President Bush was about to take a victory lap of Texas two days BEFORE the 2000 election, even as Algore was letting it all hang out and going for broke. Someone finally shook some sense into him (or his campaign) and told him that Zogby was showing him down in the popular vote (which ended up being the case). Bush instead campaigned in West Virginia and Tennessee and managed to win both by a squeaker...you just have to wonder about how much COMMON SENSE some of these campaigns have.
Try to look at it this way: he's putting Americans to work... home builders, roofers, landscapers, artisans, craftsman using his own money.
I would recommend he get four elevators - one for each car! (And maybe an extra one in case guests stop by)
This is yet one more reason why he won’t win the general election if he hijacks the GOP nomination.
