If coup makers can award themselves an amnesty against prosecution and threaten to send anyone to jail that disagrees with them, why should the opposition not think a Thaksin pardon may be possible?
Each side appears to make it up as they go along.
This is either going to be a landslide victory for Pheu Thai and the cycle of coups continues, or they fiddle the election results in favour of the current incumbents and people go out on the streets in protest.
Either way there is going to be no end to the instability that started in 2005 after Thaksin stopped them all being given billions for free from KTB.
