Blaine, who had no intention of giving Guiteau a position he was unqualified for and had not earned, simply said the deadlock in the Senate over Robertson's nomination made it impossible to consider the Paris consulship, which required Senate confirmation.[204] Once the New York senators had resigned, and Robertson had been confirmed as Collector, Guiteau pressed his claim, and Blaine told him he would not receive the position.[205]
Guiteau came to believe he had lost the position because he was a Stalwart. He decided the only way to end the Republican Party's internecine warfare was for Garfield to die—though he had nothing personal against the president. Arthur's succession would restore peace, he felt, and lead to rewards for fellow Stalwarts, including Guiteau.[206]
The assassination of Abraham Lincoln was deemed a fluke due to the Civil War, and Garfield, like most people, saw no reason the president should be guarded; his movements and plans were often printed in the newspapers. Guiteau knew Garfield would leave Washington for a cooler climate on July 2, 1881, and made plans to kill him before then.
