While ABC's "This Week" continues to search for a permanent host, former Bush strategist Matthew Dowd will guest-host the program this Sunday.
Dowd is a political analyst and ABC News contributor as well as a consultant for non-political clients. While he is best known for his work on George W. Bush's 2004 campaign, he began his career as a Democrat and publicly came out as a critic of the Bush administration.
"Since joining ABC in 2007, Matthew Dowd has provided independent and fair analysis on issues confronting the country," an ABC News spokesperson said. "He has tremendous ability to speak to and understand all sides of an issue."
Elizabeth Vargas guest-hosted this past Sunday's program; previous guest-hosts have included Jake Tapper, Terry Moran, Barbara Walters, and Jonathan Karl.
