Taiwan's former president Lee was prosecuted by the Taiwanese government.  Well done, it's kinda late but late is better than never. Lee is a greedy and shamless old fart who should see his God long time ago.
Does it have something to do with Ma's reelection next year? Absolutely, Ma has a soft dick, (my bad, I really mean he is a wimp) and we all know that. I guess he and his staff realize if he won't something dramatically to please his supporters, he may be a one-term president like Jimmy Carter.
In my two-cent opinions, Ma did a better job than our president Obama.  Obama is in a wrong time and wrong place to be the first black President in US history, but he chose this shitty position so he should be blamed. 

Ma actually did a few good things for Taiwan.  The economics in Taiwan is much better than US now. His major mistake is that he forgot who put him on the president's seat. He tried to kiss ass too hard for the people who didn't vote for him. You cannot please everybody no matter you are the president or a consultant like me. 

I will choose Ma over Tsai. DPP did such a shitty job in their 8 years administration.  For the people who still think Taiwan will be Republic of Taiwan someday and US will fight with China to help you guys to reach this goal,  you were brain damaged or had a lobotomy surgery before.   US owe China so much money; if Chinese dumps our treasure bonds in an open market, US could become a developing country.
