WASHINGTON (AP) — A Republican running in the crowded Georgia Senate primary is running ads that feature an imaginary phone call from President Barack Obama, a Democrat.

In the 30-second ad, someone who sounds like the president asks Rep. Jack Kingston to stop trying to block Obama's signature health care law.

"Kingston, let me be clear: I do not want you in the Senate," the fake Obama says as images of him appear on the screen.

Kingston is locked in a primary scramble for the GOP nomination that will be decided by the May 20 primary.

Kingston ended last year with $3.4 million in the bank, while rival Rep. Phil Gingrey had $2.3 million. Businessman David Perdue gave his campaign $1 million to end the year with $1.7 million cash on hand.
