McConnell, GOP descend on Nebraska to save Deb Fischer's endangered Senate seat

Senate Minority Leader Mitch McConnell, R-Ky., and other Republicans are coming to the rescue of Sen. Deb Fischer, R-Neb., who faces a legitimate threat to her re-election from independent Senate candidate Dan Osborn, a union leader and mechanic. 

Millions of dollars have been poured into Fischer's Nebraska Senate race in the last month as Republicans look to prevent an upset that could hurt their chances of taking the upper chamber's majority. 

The McConnell-aligned Senate Leadership Fund recently launched a $3 million ad buy in the state to shore up the Nebraska Republican's support.

"California and New York Democrats are putting crazy money into Dan Osborn's campaign. They're not going to succeed, especially as Nebraska voters learn about Osborn's Democrat ties and Bernie Sanders' ideology. We're just closing the gap a bit," Senate Leadership Fund President and CEO Steven Law said in a statement. 

The National Republican Senatorial Committee (NRSC) has also gotten involved, putting more than $500,000 into ad reservations as of the beginning of October, according to AdImpact.

Additionally, Fischer is getting help from well-known top Republican Sen. Chuck Grassley in neighboring Iowa. In a new radio ad, he tells voters, "This is your neighbor Chuck Grassley," adding, "my friend Deb Fischer needs your vote."
