New Jersey Governor Chris Christie was on the out-of-state campaign trail again on Thursday. This time Christie went to New Mexico to stump for Gov. Susana Martinez in her reelection bid. Martinez became the nation’s first Latina governor in 2011 and is expected to win again on election day. Some Republicans suggest that Martinez could be a running mate for Christie if he runs for president in 2016. Christie is chairman of the Republican Governors Association, and has also visited Arizona, Colorado and Iowa this week.
