INUNDATED: You think the repetition of U.S. Senate TV ads is bad? The chart shows it's worse in other states.

The Center for Public Integrity reports
on TV ad spending in the critical U.S. Senate battleground states — a report that shows Democratic money matching Republican money in the battle by U.S. Sen. Mark Pryor to hold his seat against Tom Cotton.

During the week following Labor Day, Democrats and their allies aired significantly more TV ads in Alaska, Georgia, Michigan and North Carolina, according to estimates from Kantar Media/CMAG.

In Arkansas, Colorado, Iowa and Louisiana, Democrats and their allies also edged out their rivals by narrower margins, airing less than 10 percent more TV ads than conservatives in each state during the week following Labor Day.

A chart shows independent groups on the Republican side have outpaced independent group spending on the Democratic side in Arkansas, making up for a party and candidate edge for Pryor.
