Election Day is going to come quicker than you know.

Long the Republican frontrunner, Mitt Romney has been gradually building momentum towards Nov. 6 since clinching the party nomination on May 29. Now, in the throes of virtually non-stop tours around the U.S. with running mate Paul Ryan, Romney moves to the next stage of his campaign next Monday at the Republican National Convention in Tampa.

Photographer Lauren Fleishman has watched Romney’s campaign evolve since she first began covering the former Massachusetts governor for TIME. Traveling with him through more than ten states since March, Fleishman became aware of how the Romney-Ryan team began to pull out the stops as the Republican National Convention loomed closer on the horizon.

This past week, as the Romney motorcade raced through Boston, New Orleans and Long Island, N.Y., TIME was granted some rare moments of behind-the-scenes access, as Fleishman tagged along with him at work on the campaign plane, and at a private luncheon with supporters.

The Romney camp, eager to reach crucial members of their party before the 2012 convention, had ratcheted up their game. Campaign events seemed grander; crowds swelled in front of more-energized-than-ever candidates. And, in as controlled an environment as the modern political campaign allows, Romney exuded a new spirit—that of Paul Ryan.

“Now that he has a running mate, the crowd gets really excited—it feels like almost twice the energy,” Fleishman said.
