House Budget Chairman Paul Ryan (R) has made television advertisement reservations in the 1st district, where he is running for re-election even as he simultaneously campaigns for vice president.

Ryan’s 1st district ad buy is set to run for the next two weeks and dovetails with Wisconsin television ads being run by Republican presidential nominee Mitt Romney and the Romney/Ryan ticket. Businessman Rob Zerban is challenging Ryan in the 1st district.

Zerban is Ryan’s most organized Democratic challenger in recent memory. But Ryan has a daunting amount of money stockpiled and newfound national notoriety, and redistricting improved the lines for him.

Roll Call currently rates this race as Safe Republican.
