Tarheeman1993 at swing state project likened a race between Beau Biden and Mike Castle to the 1972 Joe Biden race against Caleb Boggs.
Castle’s statement to the Philly Inquirer definitely stuck a half-hearted tone. Tarheeman1993 points out:
Back in 1972, Joe Biden defeated Caleb Boggs because Boggs was reluctant to run again. Castle seems to have the same feelings as Boggs did in 1972. A reluctant candidate won’t do much good for the Republicans.
Not only is he reluctant, Castle (like Boggs back in ’72) is covered with the slime of a crooked President.
Prediction: Castle retires rather than lose.
