WASHINGTON -- Nick Ayers, one of the most sought-after operatives in the Republican Party, has signed on to run former Minnesota Gov. Tim Pawlenty's presidential exploratory committee and likely presidential campaign, a sign the slow-moving GOP race is picking up steam.
Pawlenty got to know Ayers through the Republican Governors Assn., where the latter served as executive director for four years, overseeing a team that raised a record $117 million in the last election cycle.
