The Democratic Congressional Campaign Committee sent out an appeal from Sen. Kirsten Gillibrand (D-N.Y.) for donations to David Weprin's campaign late Thursday morning.

Weprin is locked in a close race in a Democratic-leaning Queens and Brooklyn congressional district against Republican Bob Turner, and the fundraising plea suggests the DCCC doesn't want to leave anything to chance.

"With the election just days away, [Weprin] is being attacked from outside groups supporting his Tea Party opponent, Bob Turner," writes Gillibrand. "This election is too important to let the Tea Party and outside shadow groups steal the race. We have the better candidate who is right on the issues. Now we just need to help him get the word out. "

The National Republican Congressional Committee sent out a similar plea for Turner Wednesday afternoon.

"This Tuesday, there is a special election to replace disgraced Congressman Anthony Weiner. What you may not know is that Republican Bob Turner can win this seat — but he needs your help," wrote NRCC Chairman Pete Sessions (R-Texas).

Turner released a poll last week that showed the race tied, prompting the DCCC to release its own internal poll showing Weprin up by 8 percentage points.

The district leans Democratic but has shifted toward Republicans, largely because of a swing in the politically conservative Orthodox Jewish community toward the GOP. After giving then-Vice President Gore 67 percent of the vote in 2000, it gave Sen. John Kerry (D-Mass.) just 56 percent of its vote in 2004. President Obama took 55 percent of the vote there in 2008.

Hawkish Jewish Democrats, including former New York City Mayor Ed Koch and Assemblyman Dov Hikind, have endorsed Turner, who is Catholic, while the Jewish Press, The New York Times and Sen. Joseph Lieberman (I-Conn.) have endorsed Weprin, an Orthodox Jew.

Neither of the national parties had engaged much in the race until this week. But as the race seems to have tightened, both are paying closer attention.
