The GOP should become the Party of Math

Surprise, surprise: Republicans don't like President Obama's new budget blueprint, particularly its $1.5 trillion in tax increases.

The GOP-controlled Congress will surely offer an alternative tax reform plan. So too, eventually, will the many GOP presidential candidates. Republicans believe the tax code matters — a lot — to the American economy's growth potential. This is the classic GOP argument: The lower top tax rates are, the faster the economy grows — and the richer everybody becomes. Sure, some will do better than others. But as Republicans like to say, echoing President John F. Kennedy in the 1960s, a rising tide lifts all boats.
