After a failed “Victory Day” over the weekend, Thai opposition protesters took to the streets on Monday to renew their fight to topple Prime Minister Yingluck Shinawatra.  Riot police used teargas and stun grenades for a second day outside her fortified office compound to keep them at bay.

The standoff pits Bangkok's urban middle class and royalist elite against the mostly poor, rural supporters of Yingluck and her brother, Thaksin Shinawatra.  He was deposed in a 2006 coup. 

The anti-government protesters are backed by the Democrat Party, which has not won an election in more than two decades and have lost every national vote for the past 13 years to Thaksin or his allies.  In the past, the military has supported anti-Thaksin forces, but this time around appears to be maintaining neutrality.

On Sunday, the protesters failed to get through concrete barricades that the police put up to protect the Prime Minister’s office.  Yingluck Shinatrawa isn’t even there – She’s been moved to a safer location – but the government wants to hold the offices as a symbol of stability.  The opposition is giving the democratically election leader until tomorrow to step down.  There’s no sign of that happening.
