Politico reports that the GOP is “fretting” over the seat of retiring liberal Sen. Tom Harkin in Iowa:
Few states are more important than Iowa in the battle for the Senate this fall. But anxiety is rising within Republican ranks that deep-pocketed conservative donors and outside groups are not doing enough, as Democrats outspend them by millions of dollars to retain the seat of retiring liberal Sen. Tom Harkin.
Since GOP nominee Joni Ernst won the June primary, Democratic Rep. Bruce Braley and his allies have outspent Ernst and her supporters by more than $2.1 million, $9.2 million to $7 million. Democratic groups have reserved $10.8 million for the final six weeks of the race, compared to $8.3 million for Republican groups, according to sources tracking the air war.
