Perhaps you didn't understand. I'll try again; Buchanan and Tancredo are allies on immigration, thus the collaboration on the PAC.
Tancredo supported the War in Iraq, Pat Buchanan did not.
Agreement and cooperation on one issue does not automatically mean agreement on all others.

Then pat if he had an ounce of principle decency would withdraw support from tancredo.
He won't though, to many bucks coming into "tancredo's" PAC, and going into the leaders pockets(pat and bay buchanan).
How long are you going to put up this charade.
