As part of its $20 million summer campaign knocking Democrats on their economic record, Crossroads GPS announced Wednesday a $3.5 million advertising effort titled “Thread.”

The ad emphasizes, visually, the concept that current economic policies could hurt future generations. The $3.5 million figure includes production, Internet advertising and ad buys on national cable TV and local network stations in Colorado, Iowa, North Carolina, New Mexico, Nevada and Virginia.

“America’s economy really is hanging by a thread, and to keep that thread from breaking, Republicans must stop President Obama’s reckless scheme to raise taxes in the middle of a jobs recession,” Crossroads GPS President Steven Law said.

This effort comes one day after the powerful conservative advocacy group launched a series of ads aimed at vulnerable Democratic Senators.
