You are absolutely correct. It's a symbiotic relationship.
Donald attacks directly the fact that Obama is not one of us. He's foreign born, raised in a foreign religion...and steeped in radical communism. He has put blood in the water most certainly.
Then Palin attacks what Obama has done WHILE IN OFFICE...how he kowtows to foreign leaders...prefers foreign energy companies over US energy companies...abandons our traditional allies etc.
Palin is in the same groove, she's just more sophisticated. She also NEEDS Trump to set the table.
Synergy.
IF the FREEP is enamored with Chump, there is no hope for Republicans.
He is more a politician than any other candidate other than Obama (who was manufactured).
He was a Nancy Pelosi fan for crying out loud. What more does anyone need to hear?
