There's a very deep rift here and I'm beginning to think there are factions on both sides who actually want a shooting war to break out.
I think Yingluck reacted as I did to the BIG protests. "Meh, they were calling for over a million people and only very generous camera work made it look like even 100,000, half of whom were bussed in for a visit to Bangkok." I've been in protests during the VN war that were about a million. There were less than a tenth of that.
I'm not sure if they think that there's so little support that they could actually wade in and disperse the demonstrators. I sincerely doubt that they can. Thai face is a big thing and if there is any indication of push coming to shove, the yellow shirt supporters will come out in droves.
Politically, though, push has already come to shove. The neo-fascists (yeah, that's what I called them) blocked the registration - not of voters, but of candidates. There may be districts with no one officially registered to run for the seat and thus no quorum when the government reconvenes. Now, rather than saying, "Well, we need an emergency act to find some way of registering your candidacy other than walking to an arena through a crowd of protesters....", they've gone to the judiciary to try to get the election blocked. They say "pushed back", but they've offered no solutions as to how/when and it's quite obviously the groundwork to declaring that "We need a committee of concerned citizens to run the country until then because the CARETAKER government can't do so."
The thing is.... the only thing stopping the EC and the judiciary is the masses supporting the red shirts. And that, traditionally in Thailand, is not enough. Someone compared this to the GOP fighting to hold onto their past and being unwilling to recognize the demographic shift. Here, the paleos have recognized that they'll never get elected again, have said so, and have declared, "So what? We still want to be the government."
Hitherto, it was only Suthep (the leader of the protests and former DP Minister In Charge of Shooting Red Shirt Demonstrators) who seemed to be pushing for someone to open fire. My feeling was that he felt that if he could get less tear gas and rubber bullets and more actual gunfire, then the military will step in. Now? I'm concerned that there's a faction in the red shirts who want the same thing.
