Could genetic drift eventually lead to speciation? why or why not

It could because when a organisms leaves a population it takes its alleles with it lowering the allele frequency

Also it occurs in smaller populations and can either rid them of alleles and make them have a lower population (bottleneck effect). Or they could possibly fix things that are wrong.

A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
