He was 66.</p><p class="css-at9mc1 evys1bk0">His wife, Marian Drum, <a class="css-yywogo" href="https://jabberwocking.com/" rel="noopener noreferrer" target="_blank" title="">announced the death on his website</a> but did not say where he died or cite a cause.</p><p class="css-at9mc1 evys1bk0">Mr. Drum, who lived in Irvine, Calif., had been diagnosed with multiple myeloma in 2014 and had recently developed pneumonia. He blogged about those personal challenges openly and with the same insight that he brought to issues like health care policy and urban planning.</p><p class="css-at9mc1 evys1bk0">He spent most of his life in Orange County, Calif., which distinguished him from the majority of early big-name bloggers, many of whom hailed from the Washington-Boston corridor or from academic enclaves.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-1"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-1"><div class="css-53u6y8"><p class="css-at9mc1 evys1bk0">Mr. Drum began blogging in 2002 and quickly developed a large nationwide following. He helped shape what became known as the liberal blogosphere, populated by a broad amalgam of left-of-center thinkers who emphasized policy debates over political horse races.</p><p class="css-at9mc1 evys1bk0">His curiosity was broad, and he wrote on a variety of subjects from a variety of perspectives — sometimes casually observational, sometimes rigorously analytical — in a way that set him apart from the assorted camps that defined the blogosphere, including academics, politicos and ideologues.</p><div class="css-1336jj"><div class="css-121kum4"><div class="css-171quhb"></div><div class="css-asuuk5"><noscript><div class="css-7axq9l" data-testid="optimistic-truncator-noscript"><svg aria-hidden="true" class="css-1b5b8u1" height="24" viewbox="0 0 24 24" width="24"><path clip-rule="evenodd" d="M2.5 12a9.5 9.5 0 1 1 19 0 9.5 9.5 0 0 1-19 0Zm8.5 1.75v-7.5h2v7.5h-2Zm0 2v2h2v-2h-2Z" fill="currentColor" fill-rule="evenodd"></path></svg><div class="css-6yo1no" data-testid="optimistic-truncator-noscript-message"><p class="css-3kpklk">We are having trouble retrieving the article content.</p><p class="css-3kpklk">Please enable JavaScript in your browser settings.</p></div></div></noscript><div class="css-1dv1kvn" id="optimistic-truncator-a11y" tabindex="-1"><hr/><p>Thank you for your patience while we verify access.
