Too many.
Actually, not enough. With three times as many reps - closer to what there should be, proportional to population growth - we would have many more strong conservatives in office and lunatics like this would be far less influential.
As it is, we get far Left characters using gerrymandering and/or ballot harvesting to get every possible Democrat and illegal vote plus just enough votes from foolish white Republican women who are "concerned about Trump's tone" to reach 51% and take the seats in moderate districts, as we saw in Orange County, CA last Fall. If OC had three times as many seats, they might go, say, 9 to 3 Republican.
