How did government grant to build railroads results in large scale corruption?

I kinda of thinking it would be cause The government was handing out large amount of money and local politicians became greedy

.elections are held to determine who serves in congress.

no statements but ok.

the statement that best describes the idea of manifest destiny that was used in the 19th century would be that "it was fate that the united states would continue to  expand westward," since people thought the us was "destined" to do so.
