Since this was written many months ago, the noose has tightened. Romney is guilty of terrible doings to build his fortune - including investments which did conscious and tangible harm. He will be forced either to put up or stagger forward, losing ignominiously.

1. Despite all his flip flops, he would aid and abet the Roberts Court, further damaging our democracy and making women prey to the reversal of Rove v Wade.
2. Despite his probable rejection of the worst of the Ryan One Percent Budget, he would steer the nation on the same W course that, with the Clinton complicity in repealing Glass-Steagall, precipitated the W meltdown.
3. The emptiness of his suit suggests that he would simply not be up to the reasoned consideration that has characterized the Obama stewardship of both our economy and our national security.
All of these reasons combine with the biggest reason of all - a Romney win would likely signal a Republican advance with all of the depredations that have characterized the governance of the states and the inaction and criminality of the GOP in the congress. This is banal, shabby, deleterious and otherwise not advisable. If the Koch PACS do not overwhelm us, and if we adopt the mantra one vote for every dollar the GOP throws at the President, we will defeat Romney and maybe jolt the sick GOP back to some approximation of sanity.
