There are just too many of them! And, it could be even more, if Taiwan has a majority government, which may come true after the December's Parliment Election.
* Just the improvement in democracy means a lot to people there- For example:
- You can say say or publish anything you like or you believe, - You don't have to be afraid to criticize the government, even sometime you don't have good reasons or any evidence at all. - Look at the way they handled the demostrations! - ...
As for other achievements, they are seriously cleanning the corruptions, a lot of constructions (which couldn't be done by the KMT government) are either finished now or going to be completeed soon.
There are just too many of them!
People realize there are still many to be done or improved, But, they can see the differences between this government and the KMT government before.
That's why they are gaining more and more support in the past many years!
