When it comes to the election's core issue—restoring a healthy economy—the key is a good tax plan and the ability to implement it. Mr. Gingrich has a significantly better plan than does Mr. Romney, and he has twice before been instrumental in implementing a successful tax plan on a national level—once when he served in Congress as a Reagan supporter in the 1980s and again when he was President Clinton's partner as speaker of the House of Representatives in the 1990s. During both of these periods the economy prospered incredibly—in good part because of Mr. Gingrich.
If that doesn't constitute an endorsement, it comes mighty close.
