Born in Boston, Massachusetts to a father who was from Argentina and a Brooklyn-born mother, Leibovich grew up in a Jewish home he describes as not religious.

[8] Leibovich is a political analyst for NBC and MSNBC, and appears regularly on Morning Joe, Deadline White House with Nicolle Wallace and Meet the Press.

[15] Leibovich discussed This Town on The Daily Show with Jon Stewart,[16] ABC's This Week with George Stephanopoulos,[17] Charlie Rose,[18] PBS's Moyers and Company[19] and NPR's Weekend Edition.

[23] Fareed Zakaria as reviewer for the Washington Post praises it as the "hottest political book of the summer", containing " juicy anecdotes" and a tell-tale core of "corruption and dysfunction".

[25] In his book review for The New York Times, novelist Christopher Buckley described This Town as a series of “mini-masterpieces of politico-anthropological sociology".

[27] This Town was released in paperback in April 2014 in conjunction with the annual White House Correspondents Dinner, which Leibovich has described as "an abomination".

[28] The book attracted controversy when an aide to Representative Darrell Issa was fired for sharing reporters’ e-mails with Leibovich without their knowledge.
