The only way the GOP could possibly become progressive is if they simply find new buzzwords and a new marketing strategy for the same old crap they've been pushing for years: increased wealth for them at the expense of the nation.

First, it's simply not true that “progressive traditionally refers to Republicans.” While Teddy R did run as a progressive, the movement predominantly felt more comfortable within the Democratic party. Woodrow Wilson was the first president that implemented a slew of progressive policies. These included the income tax, the federal reserve, and a foreign policy designed to make the world “safe” for democracy. The progressive movement simply ignored the Consitution and sought to expand the power of the presidency. Gene Healy's The Cult of the Presidency has a good discussion about how progressives sought to increase the President's power. Paul Johnson's A History of the American People also has a broader discussion about the progressive movement's impact on turn on the 20th century politics.

Second, while he didn't use the word to describe himself, we've had a progressive Republican in the White House for 8 years. The Iraq War, the Medicare prescription plan, and No Child Left Behind were all implemented to make the world a better place. That's been the problem all along! There was a time when Republicans at least pretended to understand that government's actions needed to be limited lest it created incalculable harm. The party simply does not understand that anymore. That's why it's no better than the Democrats in that sense.

Third, his emphasis seems to be more on rebuilding an effective party rather than adopting effective policies. Why should I care if I put on a red shirt instead of a blue shirt if I don't do anything differently? That distinction seems to be lost on many Republicans, particularly its leadership.

Contrary to what many say, we don't need a third party, we need a second party. If this interview is any indication, it's going to be a long time before that happens.
