One reason to choose a solidly BLUE state for the first primary [View All]

cross-party voting.

If you hold a primary in a purple or red state, EVEN with a closed primary, it is too easy for Republican forces to switch their party affiliation and vote in the primary, especially when facing a republican incumbent with no opposition.

If you choose a solidly blue state for the first primary, then there will be fewer Republicans to muck up the process, and those Republicans will in general be more moderate/liberal.
