Just in case you weren't watching, the pan-blues (the KMT, New Party, and PFP) retained their majority in the Legislative Yuan yesterday, 114 to the pan-greens' (DPP and TSU) 101. I imagine this will result in continued gridlock in the legislature, as the pan-blues do their best to make Chen (and by extension, the DPP) look incompetent as a president. This, unless the two sides manage to overcome self-interest and actually try to work together.
The Taipei Times has an editorial arguing that the "low" turnout for the election (66%, they say, but the China Post says under 60%)* had to do with people becoming "sick and tired of politics". The editorial also argues that the strategy of allocating votes (basically asking the party faithful to vote for one pan-green candidate instead of another because the former is more likely to lose than the latter) hurt the pan-greens. These claims are in contrast to analysis from sources like the PRC and CNN that have attributed low turnout and the pan-green camp's loss to Chen's pro-independence stance.
*Note as of Dec. 14: Either I've got 老花 eyes or the Taipei Times has changed its turnout figure: it now reads as 59% on the website.
