Liz Mair makes it. Here's her conclusion (in the hope that you find it compelling enough to read the whole thing.)
On a whole range of things that matter to me personally, neither of these guys will be better than the other. But Romney scores better than Obama on at least a few of my top concerns as a voter. And there is a chance, albeit not an overwhelming one from my standpoint, that he can pull out a win this week—so I am prepared to back him.
If you live in any of Colorado, Iowa, Wisconsin, Ohio, New Hampshire, Florida or Virginia, and can’t decide between Romney and Johnson or writing in, I’d urge you to have a think about the above. My rationale may not be enough to get you to push the Romney button. But it is enough for me—just.
And Mitt, if you happen to read this and if you do prevail on Tuesday, please know that I’ll be enthusiastically in the bag for a second term if you really do slash spending, bring down the deficit, reform entitlements, reform the immigration system, ditch the worst aspects of Obamacare and Dodd-Frank, govern like a free-trader, and hold to the general status quo on social issues. Oh, and have lunch with Paul Ryan weekly and take him seriously.
