The Club for Growth's independent expenditure arm has started airing television spots again on behalf of Rep. Justin Amash, R-Mich., according to Federal Election Commission records.  

The move could be indicative that Amash is in some political jeopardy just days ahead of the August 5 primary.

No House Republican enrages the business-friendly wing of the GOP more than Justin Amash. But members and operatives who hoped to end his political career are running out of time and moxie before Michigan's Aug. 5 primary.  

So far, many of Amash’s cash-flush critics have passed on investing substantial resources in his GOP rival, former East Grand Rapids School Trustee Brian Ellis. At the same time, Amash allies such as the Club for Growth and Sen. Ted Cruz, R-Texas, have tangibly backed the libertarian sophomore's re-election in the 3rd District.

The U.S. Chamber of Commerce endorsed GOP Rep. Justin Amash's primary challenger in Michigan's 3rd District.  

The group's support could translate into television airtime for Brian Ellis, a former East Grand Rapids School Trustee, before the Aug. 5 primary. The primary has become one of this cycle's top battles inside the GOP, with the party's libertarian wing backing Amash and national business interests boosting Ellis.  

Club for Growth Makes Big Ad Buy to Boost Amash

The Club for Growth has sponsored a major television and radio ad buy to boost Rep. Justin Amash, R-Mich., who faces a primary challenge in the 3rd District.

In the television ad, released on Wednesday, the club hits Amash's primary rival, former East Grand Rapids School Trustee Brian Ellis, for various votes he took in that role. The conservative group also seeks to tie Ellis to former Gov. Jennifer Granholm, a Democrat, in the spot.

Daily Ad Track

Live in a competitive district? It is nearly impossible to turn on the television and not see ads with seniors, tying a candidate to President Barack Obama, House Minority Leader Nancy Pelosi (D-Calif.) or Republican presidential nominee Mitt Romney.

But not all ads took the cookie-cutter approach. Here is what cut through the clutter today:

House Race Ratings: Changes in Michigan and Washington

House Democrats had a productive primary night Tuesday. But how good was it, really?

In Michigan, Democrats nominated their strongest possible general election candidate, a self-funding former state lawmaker, to challenge freshman Rep. Justin Amash (R) in the 3rd district. Another potential opportunity was solidified in the vacant 11th district, where Republicans nominated a libertarian reindeer rancher who is untested and unvetted as a candidate. Finally, on the West Coast, Democrats nominated the best possible candidate, former Microsoft executive Suzan DelBene, in Washington's vacant 1st district.

Michigan: Filing Deadline Arrives With No Surprises

Rep. Tim Walberg (R) will not have a top challenger for his re-election race this November, leaving Democrats with a major recruitment hole in the Michigan map.

Instead, Democrats will focus their efforts on a rerun race between freshman Rep. Dan Benishek (R) and former state Rep. Gary McDowell (D) in the state's Upper Peninsula.

Michigan: Another Democrat Challenges Justin Amash

Former state Rep. Steve Pestka announced Monday that he will seek the Democratic nomination to challenge Rep. Justin Amash (R) in the fall.

“I want to give back to the community that has given us so much by restoring our voice in our nation’s Capitol, where I will never forget those West Michigan values,” Pestka said in a statement.
