Joe Biden had an End of Irony moment last night

[George II]

61. Of course the details of where the money came from is always ignored to make it look worse...

Most of that industry, employer data comes from opensecrets.org.

You should look at how they determine where money comes from and their caveats. I'll help you out, it's posted below. Of course you can choose to interpret this any way you want or ignore what you don't like. The reason we don't know as much about Sanders' source of money is that more than 70% of his contributions (tens of millions of dollars) are "un-itemized"! We don't know the occupation or employer of the source of almost three quarters of his revenue, so no one can scrutinize it as deeply as some like to do with Biden and other candidates.

Why (and How) We Use Donors' Employer/Occupation Information

The organizations listed as "Top Contributors" reached this list for one of two reasons: either they gave through a political action committee sponsored by the organization, or individuals connected with the organization contributed directly to the candidate.

Under federal law, all contributions over $200 must be itemized and the donor's occupation and employer must be requested and disclosed, if provided. The Center uses that employer/occupation information to identify the donor's economic interest. We do this in two ways:

First, we apply a code to the contribution, identifying the industry. Totals for industries (and larger economic sectors) can be seen in each candidate and race profile, and in the Industry Profile section of the OpenSecrets website.

Second, we standardize the name of the donor's employer. If enough contributions came in from people connected with that same employer, the organization's name winds up on the Top Contributor list.

Of course, it is impossible to know either the economic interest that made each individual contribution possible or the motivation for each individual giver. However, the patterns of contributions provide critical information for voters, researchers and others. That is why Congress mandated that candidates and political parties request employer information from contributors and publicly report it when the contributor provides it.

In some cases, a cluster of contributions from the same organization may indicate a concerted effort by that organization to "bundle" contributions to the candidate. In other cases—both with private companies and with government agencies, non-profits and educational institutions—the reason for the contributions may be completely unrelated to the organization.

Showing these clusters of contributions from people associated with particular organizations provides a valuable—and unique—way of understanding where a candidate is getting his or her financial support. Knowing those groups is also useful after the election, as issues come before Congress and the administration that may affect those organizations and their industries.

The bottom line is that as much as you imply (there's that word again!) that the source of Biden's or any other candidates you don't favor is nefarious, every single penny collected is legal and within FEC permissible limits.

Now about those millions of "un-itemized" dollars, hmmmm....
