Lonegan remains the heavy underdog to Democrat Cory Booker in the race to replace deceased Sen. Frank Lautenberg (D-N.J.), but recent polling seems to indicate he's narrowed Booker's lead somewhat in the final stretch of the campaign.

Still, with just over two weeks left until Election Day, it will be difficult for Lonegan to make up for lost time. He's had trouble raising money and hasn't had much of an on-air presence, and is still a relative unknown compared to Booker.

Perry's visit to the state will help him raise his profile, but it won't turn New Jersey any redder — the state went for President Obama with nearly 60 percent of the vote in 2012.

And Booker's bringing in a star of his own party to help him seal a win: Vice President Biden, who will campaign with Booker five days from Election Day.
