Han lose to Tsai by 20 percent which is difficult to win back
About 70 percent had expressed inability to accept ccp-related candidate, so unless Han make decisive moves to cut off his links from pro-China factions it is impossible for him to win.
If a moderate blue joins in a three way fight, it will drain away that 30 percent that Han have becos extreme blue/red support is only 0.5-1%
If a white, orange or non-colored joins, it will draw from both Han and tsai, but the fear of Han betraying tw means that the impact on tsai will be less than han.
If a deep green joins, it will hurt tsai more. But they are sensible enough not to let Han win as that will hurt tw more. Anyway this is not happening.
So it means Han is 死路一条。 anyway win or lose, if he pleases his master sure got benefits one so no scared
