iWatch reports. An important aspect of this story is pressure to fundraise created by super PACs:

Scandal-plagued Alabama Rep. Spencer Bachus is fighting for his political life in Tuesday’s primary, but not everyone has given up on him — the chairman of the House Financial Services Committee can still count on his friends in the credit union industry.

CUNA, the Credit Union National Association, spent nearly $28,000 on last-minute radio ads supporting the Republican congressman, one of the most influential lawmakers in Washington when it comes to regulating the financial services sector.

Bachus hit the headlines last month when he was featured on “60 Minutes” and in a book for allegedly using inside information to make trades on stock options, prompting an investigation by the Office of Congressional Ethics.

Making matters worse, Bachus has been on the receiving end of more than $200,000 in attack ads from an upstart super PAC called the “Campaign for Primary Accountability,” a Texas-based group that has been critical of incumbents in several districts across the country.
