Michael Franc has an interesting piece on NRO about the demographics of campaign contributions. The gravamen is that Democratic presidential candidates in the current election have exhibited a whopping advantage among all kinds of elite groups, identified by professional, financial, or educational status. Meanwhile, Republicans garnered more support from plumbers, truckers, and janitors.

Franc doesn’t make much of an effort to explain the phenomenon, other than to note that Democrats have enjoyed a $200 million advantage in general, which may go a long way toward generating the more specific category advantages. And which may further be explained (this is my speculation) as being due to a) more people thinking a Democrat will win the White House and wanting to support a winner, or b) the Democratic primary race being petitive than the Republican, or c) bination of the two.

Instead of positing explanations, Franc focuses on what the trend may mean for the respective parties’ conventional policy tendencies:

What should we make of all this? National political parties, after all, reflect their supporters, and party leaders traditionally feel a responsibility to cater to their supporters’ whims. A party that receives overwhelming support from elite Wall Street investment firms, corporate bigwigs, and highly educated professionals may find it exceedingly difficult to raise their taxes or impose draconian new Big Government regulations on them. Similarly, a party that is losing well-educated suburban professionals and gaining support from blue-collar workers may find it more difficult to support free trade agreements and embrace globalization.
