U.S. Reps. Gabrielle Giffords and Harry Mitchell are among 40 Democrat junior members of the House the Democratic Congressional Campaign Committee has decided, as a precaution, are vulnerable in 2010.

The DCCC has developed a program called "Frontline" that is designed to protect the most at-risk incumbents. Frontline pushes members to focus on fundraising and outreach, and freshmen, such as U.S. Rep. Ann Kirkpatrick, are put in an early position to avoid Republican attacks.

Vulnerability is somewhat decided by the margin of wins in the 2008 election.

More senior members who still represent districts President Bush or U.S. Sen. John McCain won find themselves on the list as a precaution, despite winning by comfortable margins.

The DCCC said the Frontline program likely will "graduate" the members to "good bets for re-election."

Jeff Stapleton at state Democratic headquarters dismissed the DCCC account and went after the GOP. "Instead of working together to get our economy back on track, national Republicans are out to get the most effective and hard-working members of Congress that Arizona has in Washington: Harry Mitchell and Gabrielle Giffords," he said. 

Also, David Schweikert has announced he will make another run in Arizona's 5th Congressional District.
