> tmp_df$Democratic[order(tmp_df$Democratic)]
[1] "1"   "227" "71"

What am I doing wrong? I would like the order below. I suspect the problem
lies with that NA to the left that R inserted somewhere along the line. So
how to reorder dataframe rows? Or get rid of that NA?
2      2904 Open Seat          1                0                15
3      2905 Open Seat         71              202               497
NA     2903 Open Seat        227              245              2035

Thanks,
