Republicans are well positioned to win the 2016 presidential contest for a number of reasons: Our economy is soft, a majority of the public is deeply frustrated by the pace of growth and President Obama's job approval rating is stuck in the mid 40's. This is never good for the incumbent party.
What's more, the leading Democratic candidate, Hillary Clinton, is seen as dishonest and untrustworthy by a majority of the general electorate, especially Independents. On it's face, Republicans should win in November.
But, primaries matter. And, right now the GOP field is too crowded to ensure the party puts forward its strongest, most electable candidate. The bottom line is at least a couple candidates need to drop out after the South Carolina primary.
