MIAMI- Less than one month before the November election and there has been a significant shift in one of the most widely watched congressional races in the Sunshine State.

According to the venerable Cook Political Report, the battle for the Eighth Congressional District, currently held by Democrat incumbent Alan Grayson, has changed from "Toss up" to "Lean Republican," following what the political analysts at Cook call a "toxic" atmosphere due to some of the controversial tactics used by Grayson against his Republican rival, State Sen. Dan Webster.

"Like a bad disease, this race is so toxic thanks to Grayson that both parties wish they could quarantine it," The Cook Political report reads in its latest analysis of the race.

In recent weeks, Grayson had been criticized by Democrats and Republicans alike for a TV ad calling Webster "Taliban Dan," comparing his conservative Christian background to the austere theology of the Taliban in Afghanistan. The controversy over the ad ignited a boost in fundraising for Webster's campaign.
