Table schema:
CREATE TABLE table_name_47 (kilgore__r_ VARCHAR, date VARCHAR, potts__i_ VARCHAR, kaine__d_ VARCHAR)

Question: What was Kilgore's percentage when Potts (I) had 4% and Kaine (D) 47%, in the poll from October 30, 2005?
SQL: SELECT kilgore__r_ FROM table_name_47 WHERE potts__i_ = "4%" AND kaine__d_ = "47%" AND date = "october 30, 2005"
