On
Meet the Press Sunday, Chuck Todd asked Susan Collins how she could support a huge tax cut after having complained about excessive debt. “Economic growth produces more revenue and that will help to offset this tax cut and actually lower the debt,” she calmly replied. An incredulous Todd asked Collins how she could defend such a claim when every study has concluded the opposite. She cited Glenn Hubbard, Larry Lindsey, and Douglas Holtz-Eakin.
Jennifer Rubin got ahold of two of the three, Hubbard and Holtz-Eakin. Both economists denied having ever claimed the Republican tax cuts would produce enough growth to recoup the lost revenue.
This is a small moment that reveals a great deal about the relation of the Republican Party to the field of economics. Hubbard and Holtz-Eakin represent the right wing of the economic profession. Both of them have long worked closely with the party and have deep sympathy to its ideological orientation. Collins, on the other hand, represents the left wing of the Republican Party. She is indisputably the most moderate — and, arguably, the
only moderate — member of her Senate caucus. And yet, on taxes, she maintains a position farther right than any serious economist can maintain. The beliefs of Republican officials and real economists are non-overlapping circles on a Venn diagram.
