It is a busy week on the campaign trail for Sen. John McCain (R-Ariz.). Except this time around, he is hitting the trail in support of others in his party.

On Monday, he endorsed former WWE CEO Linda McMahon in Danbury, Conn., for her Senate bid to replace McCain’s friend, retiring Sen. Joe Lieberman (I), according to the Hartford Courant. McMahon faces Rep. Christopher Murphy in a race that Roll Call rates as Leans Democratic.

Today and Wednesday, McCain will campaign across Florida on behalf of Mitt Romney’s presidential campaign. That tour will include mostly veterans events in Pensacola, Niceville, Panama City and Tallahassee.
