The attitudes of pan-green and pan-blue supporters toward the economic cooperation framework agreement (ECFA) the government wants to sign with China and renegotiation of a agreement with the US on US beef imports were likely to be as polarized as their political beliefs, a poll expert said yesterday.

Tsai Chia-hung (蔡佳泓), an associate research fellow at National Chengchi University’s Election Study Center, said his study showed that pan-blue supporters were likely to support an ECFA and oppose holding new rounds of negotiations on the relaxation of restrictions on US beef and beef products. Their position on the two issues, however, would not be as firm as their pan-green counterparts, Tsai said.
