Rep. Patrick Murphy’s campaign made its first ad buy Monday in Florida’s 18th District, reserving $1.4 million in cable and broadcast in the West Palm Beach-Treasure Coast media market, according to figures shared first with CQ Roll Call.  

The Democrat’s buy runs through the summer and into the fall in this district, located in the northeast corner of Palm Beach County, according to his campaign.  

The freshman is a fundraising powerhouse, bringing in $759,000 in the second quarter and reporting more than $2.6 million in cash on hand as of June 30.  

Murphy defeated former Rep. Allen B. West last cycle by less than 1 point. At the same time, the district voted for Republican presidential nominee Mitt Romney with 52 percent, making Murphy one of nine Democrats to represent a district Republicans carried in the presidential race last cycle.  

Six Republicans are vying for the GOP nod to take Murphy on in the fall in Florida’s Aug. 26 primary, however all six would start at a serious cash disadvantage .  

The National Republican Congressional Committee has not yet reserved television advertising here in the fall, either.  

Florida’s 18th District is rated a Democrat Favored district by the Rothenberg Political Report/Roll Call.
