What’s going on right now
Currently, there are two major candidates for the DNC chairmanship: Rep. Keith Ellison (D-Minn.) and Labor Secretary Tom Perez. Ellison and Perez represent two distinct wings of the Democratic Party. Ellison is seen as a liberal — one marker: he has the support of Sen. Bernie Sanders — while Perez is seen as the candidate of the party’s more centrist Obama-Clinton wing.
On the Republican side, McDaniel will replace Reince Priebus, who will serve as Trump’s chief of staff. She represents the traditional GOP. She worked in a variety of election campaigns before becoming chair of the Michigan GOP in 2015. She’s part of an important lineage in GOP politics: Mitt Romney is her uncle, and George W. Romney, the governor of Michigan in the 1960s, was her grandfather.
Why the DNC and the RNC matter
The DNC and the RNC are important because they help organize presidential election campaigns, raise and distribute money among candidates across the country, provide campaign advice, and promote the national parties through massive ‘educational campaigns’ intended to produce party brands.
Scholars disagree, however, about how much power national committees actually have over their party. Some political scientists have concluded that the DNC and the RNC are “service providers” that help candidates but are otherwise powerless because they lack control over candidate selection.
Why there’s a battle on the Democratic side
Here’s a key fact: The national committees are much more active in shaping the party when their party is out of the White House. Because they are not under the control of a president, the out-party’s chair does more to decide what the party committee does. This raises the stakes for the selection of the chair.
In contrast, “in-party” chairs serve at the pleasure of their president — and so they must support the president. History shows that although out-party chairs frequently serve four-year terms, in-party chairs serve shorter terms. For example, Richard Nixon appointed three committee chairs, Bill Clinton five, and George W. Bush six. Presidential power in this regard is almost absolute: Ronald Reagan even appointed daughter Maureen co-chair of the RNC in 1986 — to the frustration of many Republicans.
What to expect under a Trump presidency
The selection of McDaniel is only a minor victory for traditional Republicans. McDaniel will lead the party only as long as Trump approves. Because Trump has manifested little interest in intraparty politics and because Republicans have unified control of government and a majority of governorships, the RNC is likely to play only a minor role in the Trump era.
But the opposite may be true for the DNC. Without a president in office and with minorities in Congress, the next DNC chair will have more incentive to use the position to revitalize the Democratic Party.
This explains why Democratic leaders are so invested in the race for DNC chair. If Ellison wins, the DNC will probably focus on blue-collar white voters who turned their backs on the Democrats. If Perez wins, the party will focus on the coalition of minorities and highly educated voters that helped Obama win in 2008 and 2012.
