In my latest post on the WI-8 fundraising numbers, a commenter noted that perhaps we should discount the fundraising of Republican candidates Reid Ribble, Marc Trager, and Roger* Roth because they have taken money from PAC's.
As I responded to the comment, the PAC money of these three combined doesn't even begin to compare to Kagen's reliance on PAC money. The total of all PAC contributions in this race is about $570,000, of which Kagen has received about $540,000, absolutely dwarfing the PAC money of the Republicans.
Given this state of affairs, Kagen's ability to self-finance a campaign will probably never be a factor and I really don't see anything wrong with the modest amount of PAC contributions that some on the Republican side have accepted.
*4/22 12:14 I mistakenly identified candidate Roger Roth as Ryan, his brother. This has now been fixed. As someone with two brothers who also have names that start with J, I ought to be on the lookout for those types of mix-ups.
