Lenroot attended the 1920 Republican National Convention at the Chicago Coliseum , and after the selection of Harding as the nominee for President , party leaders decided that the progressive Lenroot would be a balance to a ticket with the more conservative Harding . By Saturday night , June 12 , many of the delegates had gone home , along with most of the party bosses . After Lenroot 's name had been placed in nomination and seconded but before a vote could be taken , an Oregon delegate , Wallace McCamant , nominated Coolidge for vice president . Unfettered by party bosses , the delegates weighed in for Coolidge , who received 674 votes to Lenroot 's 146 , and won on the first ballot
