This Super PAC, the Senate Leadership Fund, was founded by former aides of Senate Majority Leader Mitch McConnell. It stands to fight the Democratic Super PAC, Senate Majority PAC, which is run by former staffers of Senate Minority Leader Harry Reid.
The Senate Leadership Fund reserved $6.2 million to run ads for 3 weeks in October. This was part of an overall ad buy totaling nearly $40 million by the PAC targeting other crucial Senate races across the nation.
Pennsylvania’s Senate race is crucial for determining the make-up of the next Senate. Currently, Republicans have a 54-46 advantage (counting 2 independents who caucus with the Democrats). Thus, Democrats will have to pick up 4 seats if Hillary Clinton also wins in November, or 5 seats if Donald Trump proves victorious.
Thus, there is a big focus on Pennsylvania’s race as neither party has much room to spare. Consequently, it is expected that PA will have one of the most expensive Senate races this year. All of this happens as the latest PPP poll has the race at an effective dead heat with Toomey leading by a single percentage point 40-39.
