A source in the campaign of Doug Hoffman, the Conservative Party candidate in the three-way NY-23 special election, tells us that another member of Congress will be endorsing Hoffman: This time, it's Rep. John Linder (R-GA).

Linder will be the third sitting member of Congress to openly back the Conservative Hoffman over the moderate Republican Dede Scozzafava, following Rep. Michele Bachmann (R-MN) and Rep. Todd Tiahrt (R-KS).

Late Update: Linder's office has confirmed the endorsement. Here's Linder's statement:

"The biggest concern I have with the Republican candidate in this race is that her long held positions on unions, taxes and spending incline me to believe that she will give Nancy Pelosi a Republican vote so that these many outrageous grabs for power and control will be called 'bipartisan.' I am confident that Doug will not do that."
