In Illinois, 8th District Rep. Tammy Duckworth has raised more than vulnerable GOP Sen. Mark S. Kirk and fellow Democrat Andrea Zopp. Duckworth hauled in $1.46 million to Kirk’s $1.05 million. She ended the period with $2.8 million on hand, compared to Kirk’s $3.62 million.
The biggest surprise came in Arkansas' safe Republican Senate seat. Less than a month after launching his campaign, wealthy former U.S. attorney Conner Eldridge reportedly raised $403,000 to Sen. John Boozman’s $359,000. Boozman, however, still holds the cash advantage with $1.12 million in the bank. Because House candidates generally raise less money than their upper chamber peers, it’s less unusual for them to out-raise incumbents.
