Fundraising wrap-up: McCaskill, Dold post big quarters

Sen. Claire McCaskill (D-Mo.) and Rep. Robert Dold (R-Ill.), two incumbents facing tough reelection campaigns, posted big fundraising quarters Tuesday. Here's Tuesday's fundraising wrap-up:

• McCaskill raised $2.3 million and had approximately $6 million on hand as of the end of March, a big improvement over the already strong $1.4 million she raised last quarter. She faces a tough race in the Republican-leaning state.

• Dold (R-Ill.) raised $600,000 and has $1.6 million cash on hand, strong numbers for the endangered incumbent. He's running in a Democratic-leaning suburban Chicago district where air time is expensive.

• Rep. Betty Sutton (D-Ohio) narrowly outraised Rep. Jim Renacci (R-Ohio) in a Republican-leaning district pitting the two against each other. Renacci maintains the cash edge with $1.2 million in the bank to Sutton's $750,000.
