During these sessions the Federalist Party was so small and weak that partisan divisions mattered much less than the personal relationships that developed among the members. McLane quickly became a friend and admirer of William H. Crawford and Martin Van Buren, and at the same time became an opponent of Henry Clay and John Quincy Adams. These friendships were based more on personality than policy agreement, and were so important that McLane was one of Crawford's strongest proponents in the presidential election of 1824. Once Crawford returned to Georgia, McLane, Van Buren, and the other Crawford supporters fell into the party of Andrew Jackson. This was all the easier for him given his existing friendship with Martin Van Buren, who became his mentor and advocate.
