South Korean President Park Geun-hye entered what could be her last day in power Friday, as lawmakers geared up for what’s widely expected to be a successful impeachment vote amid a corruption scandal that has left her isolated and loathed.

The opposition feels confident that they’ll get an impeachment Friday, the last day of the current parliamentary session, because dozens of members of Park’s ruling party have said they’ll vote against the woman who was once their standard bearer.

It’s possible that the vote could be delayed or fail, but lawmakers from both parties face huge pressure to act against Park, the daughter of a military dictator still revered by many conservatives for lifting the country from poverty in the 1960s and 1970s.

On Friday morning, as lawmakers began to arrive at the parliament, hundreds of protesters, some of whom spent the night on the streets after traveling from other cities, rallied in front of the National Assembly’s main gate and urged impeachment. The crowd was expected to grow as the vote neared.
