Senate Democrats, especially Sen. Claire McCaskill, D-Mo., are the target of a strong new ad from the National Republican Senatorial Committee (NRSC), rolled out today to commemorate the big spending that gave the United States a $15 trillion national debt as of today.

“The federal debt has now hit the once-unfathomable mark of $15 trillion – a 74 percent increase and more than $48,000 for every American man, woman and child,” over the last four years, noted the NRSC press release.
