Florida Gov. Charlie Crist -- an former Republican -- has hired another Democrat to work on his independent Senate campaign.

Crist brought Josh Isay aboard his campaign to work in his communications shop, according to the USA Today

Isay formerly worked for one of the top Democrats in the Senate, Charles Schumer (N.Y.)

The Florida governor is running against former Florida House Speaker Marco Rubio (R) and Rep. Kendrick Meek (D) in November.

Crist hired Eric Johnson, a former staffer for ex-Rep. Robert Wexler (D-Fla.), to serve as his political director late last month. Crist has been trying to build up his staff since he left the Republican Party and launched an independent bid in late April.

Isay has also worked for politicians who have switched parties; namely New York City Mayor Michael Bloomberg (I) and Sen. Joe Lieberman (I-Conn.), who still caucuses with the Democrats.
