Yesterday was the last day for effective “Sunday Show campaigning” prior to the Iowa Caucuses. Former Massachusetts Gov. Mitt Romney used the day to appear with Chris Wallace in a wide-ranging interview on the Fox that left most observers impressed and his momentum from Thursday night’s debate intact.

“Hitting it out of the park,” tweeted former GE CEO Jack Welch of Romney’s performance, which is exactly the sort of walk-off review you like to bank heading into a two-week near-hiatus from the campaign as the country celebrates Christmas and New Year’s.
