Can Greuel erase a 10-point deficit in 4 weeks?

Sure she can - at least in theory. But making up such a large margin (we're assuming that the new LAT/USC poll is on the money) requires a charged, dynamic race, and the Greuel-Garcetti face-off has been anything but. Here you have two dullish campaigners presenting a hazy, largely similar vision for the city, and an electorate that doesn't much care about any of it. There's one question the pollsters should have asked: If the candidate you're not supporting ends up winning, would you be devastated? Would you even be unhappy? That's a big problem for Greuel - her opponent is perceived as perfectly competent to be mayor, and the polling results going back to early in the year consistently give him the edge (though I have to believe the race is closer than a 10-point spread). Whether it's five or 10 points, Greuel has been unable to break through, and if it hasn't happened in the last five months you have to wonder how it's going to happen in the next four weeks.
