Republican presidential candidate, former Florida Gov. Jeb Bush in Tampa, Fla. One year before Election Day 2016, Republicans are consumed by uncertainty and infighting while Democrats are coalescing behind Hillary Rodham Clinton. But there's a long way to go.

WASHINGTON — After a devastating loss in the 2012 presidential election, the Republican Party entered a period of intense self-reflection. It emerged with a vow to avoid a long and vicious 2016 primary. It concluded must embrace an overhaul of the nation's immigration laws. It should adopt a more welcoming tone to win over women and minorities.

Yet a year from Election Day 2016, the GOP primary is a rough and bumpy competition. And there are few signs the candidates are committed to expanding the party's appeal beyond its conservative base.

Meanwhile, there's no such drama among Democrats. The party appears to be coalescing behind Hillary Rodham Clinton. That's allowing the party to begin building a campaign operation aimed at turning out the general election voters who catapulted Barack Obama to victory.
