New poll data from Public Policy Polling:
Claire McCaskill's endured a lot of bad press over the last two months since PPP last polled Missouri, but at least in the short term it doesn't appear to be affecting her prospects for reelection. McCaskill's approval rating in early March was 46% and now it's still 46%. McCaskll had small leads over a cadre of potential Republican opponents in early March and she still has small leads over all of her potential foes. This continues to look like a toss up race, as it has for months now, but McCaskill's position now is no worse than it was before the issue of her airplane and its related taxes hit the news.
