Updated 12:02 p.m. | The ad war in Florida’s 13th District special election has officially begun.

The National Republican Congressional Committee has reserved about $725,000 in broadcast and cable advertising from Wednesday until Feb. 10 to support the GOP nominee, lobbyist David Jolly, according to two sources — a Democrat and a Republican — who track media buys. 

This is in addition to a nearly $100,000 digital media buy the NRCC made last week.

But the Democratic nominee, Alex Sink, is far from underfunded when it comes to ad spending. As of last week, her own campaign had placed a little more than $300,000 in ad reservations. Additionally, the Democratic Congressional Campaign Committee reserved about $200,000 in television ads last week.

The general election will take place on March 11 in the race to replace the late Republican Rep. C.W. Bill Young, who died in October.

The race is rated Tossup by Rothenberg Political Report/Roll Call.

The news of the six-figure buy was first reported by the St. Petersblog.
