(CNN) - Former President Bill Clinton is once again lending assistance to embattled Democratic Senator Blanche Lincoln, who is in a fight for her political life in her home state of Arkansas.
Clinton stumped for Lincoln during a dramatic primary election in which Lincoln narrowly clinched the Democratic nomination after a runoff against Arkansas Lt. Gov Bill Halter.
In an email sent on Tuesday, Clinton appeals to Lincoln's supporters for donations, touting Lincoln's Senate credentials and writing "I know I am preaching to the saved."
Additionally, Clinton eviscerates the Republican Senate nominee, four-term Rep. John Boozman, for his position on taxes, Medicare and social security.
In the email, Clinton acknowledges Lincoln's precarious position; "I've seen the polls and yes, this is going to be a tough fight," he writes.
A recent Mason-Dixon poll of likely Arkansas voters indicated that Boozman holds a 17- point lead over Lincoln. Other recent surveys suggest that Boozman's lead is even larger.
