It will be very hard to keep it non-violent. Don't forget that nearly half the country voted for him and is very happy with what he's doing. There are likely to be counter-protests and the two sides are likely to clash, resulting in violence.
As an aside, remember that a revolution has *never* succeeded if at least part of the armed forces (police, military) haven't joined the revolutionaries. There doesn't have to be an armed clash - but at least the silent support of the armed forces is needed.
