McMahon's $500K quarter?

Rumors are circulating that Mike McMahon may report anywhere from $400- $500,000 for his first quarter, really his first month. When I heard $400,000 I thought that number was exceptionally high but recent reports are claiming even more. If true here is some perspective on how that rate of fund raising matches up for Democratic challengers across the country;

John Adler (NJ-03) $720K
Dan Seals (IL-08) $635k
Dina Titus (NV-03) $570K
Linda Stender (NJ-07) <$500K
Suzanne Kosmas (FL-24) $475K
Dan Maffei (NY-25) ~$470k
Michael Skelly (TX-07) $412K, added
Debbie Halvorson (IL-11) $400K

McMahon would fall in line as the fourth or fifth most prolific fundraiser (so far) for a Democratic challenger this past quarter. Dina Titus has raised her $570K in just two months, after entering the race late. Everyone else on this list raised their totals over three full months. McMahon by comparison will have been raising money for roughly one month.

Question: How much if any of McMahon's money is for the primary vs. the general?

thanks to Swing State Project's fund raising round ups for making this convenient.

update: I am adding new candidates as their numbers are released.
