CEDAR RAPIDS, Iowa — Hillary Rodham Clinton’s campaign says it has bought $7.7 million worth of television air time in early primary states, making its first ad buy of the 2016 election.

The campaign says it has reserved time starting in early November through the first caucus and primary elections in early February, but it could broadcast the spots sooner if necessary.

In Iowa, where caucus goers cast the country’s first ballots, the campaign paid $3.6 million for time in all eight media markets that serve the state. An additional $4.1 million of airtime was purchased in New Hampshire, which holds the first primary.

The lead contender in the Democratic field, Clinton is campaigning in Iowa before a state party fundraiser with her nomination rivals.
