He has 90% approval rate on the opposition owned polls, and he has supermajority of the assembly for a reason, 30 years of pure corruption without any consequences by the previous governments, you'll not find enough people to oppose him to fill a boulevard.
The new assembly just passed a bill finally allowing Salvadorans in other countries to vote in all future elections, if that's not democracy I don't know what is, if the opposition is against the overwhelming support he has, maybe they should've done things right by the people in those 30 years, but they didn't and they're finally out.
And it was done democratically, by the people without a single protest.
Read into what the traditional parties did to try to block Bukele for running for president, they closed a political party overnight with a congressman from that party still in the assembly, which was unconstitutional, but nobody said a word there.
