He resigned his seat in 1908 by taking the Manor of Northstead in order to re-fight the constituency on behalf of Sinn Féin. In the resulting by-election, he was defeated by Francis Edward Meehan, the IPP candidate. After losing the by-election, Dolan emigrated to Saint Louis, Missouri, then a center of shoe manufacture.
He hoped to export that technology and set up a shoe factory in Leitrim, but was not successful.
He continued to agitate on behalf of an independent Ireland and against the entry of the United States into World War I.
He became a law professor and died in 1963.
