3. "On the question of fast-track authority ...only Democrats that identify as “liberal” strongly favor

the idea." (From your second link.)

On the question of fast-track authority, 62 percent of respondent opposed the idea, with 43 percent “strongly” opposing it. Broken down by political affiliation, only Democrats that identify as “liberal” strongly favor the idea. Predictably, a strong Republican majority oppose giving the president such authority, with both conservative and moderates oppose it by a ratio of 85 percent or higher. And perhaps most important: 66 percent of respondents who identified as independent, meaning they have no party affiliation and are a key voting constituency, oppose the idea.

Polls show that most of the opposition to fast track and TPP come from republicans, particularly from the most conservative wing of their party. Tea partiers have a name for it: Obamatrade.

On the issue of trade agreements, divisions within the Republican Party are again apparent. Staunch Conservatives are strongly opposed to granting the president fast-track authority: 76% oppose, only 22% favor. Moderate Republicans and Populist Republicans also oppose this proposal; however, their opposition is more muted. Among Moderate Republicans, 53% oppose, 43% favor; among Populists, 57% oppose, 35% favor.

Democratic groups are more united on this issue. Roughly 50% of Liberals, Socially Conservative Democrats and Partisan Poor favor fast track.
