President Obama on Tuesday nominated two major campaign bundlers to two of the most prized ambassadorships available anywhere – London and Rome – part of a pattern that has seen him reward at least 18 top fundraisers with plum diplomatic positions since 2009.

The White House said the post of ambassador to the United Kingdom will go, subject to confirmation, to Matthew Barzun, an Internet pioneer and investor who served as the Obama campaign finance chairman in 2008, as ambassador to Sweden from 2009-2011, and then again as finance chairman for the president’s 2012 campaign.
