Outside money pours into 8th District

The 8th Congressional District was already one of the biggest recipients of outside money in North Carolina. Now it's one of the biggest in the country.

Today a group called the American Action Network is dropping $300,000 into TV ads targeting Republican Scott Keadle. He faces Richard Hudson in Tuesday's GOP runoff. The Network is one of two party establishment groups helping Hudson, a former Capitol Hill staffer, in the runoff.

The YG Action Group, associated with House Majority Leader Eric Cantor, has poured in more than $400,000 on Hudson's behalf this month alone.

But Keadle isn't defenseless.

The Club for Growth has spent around $700,000 on ads supporting him and opposing Hudson.

According to the Center for Responsive Politics, only three districts in the country have seen more outside spending.
