No states share electoral votes. Each state has at least 3 or more.
Each state has electoral votes equal to the total of the 2 representative the state has in the U.S. Senate plus the number of representative the state has in the U.S. House of Representatives. The District of Columbia gets 3 electoral votes. Therefore, the total number of electoral votes is 538 - 100 (senators) + 435 (representatives) +3 (for DC).

In both states, the state at large has two electoral votes elected unti multiple-winner plurality. Each congressional district in these states also has a single electoral vote allocated using single-winner plurality, making it possible for the state to give electoral votes to multiple candidates.

Electoral votes are not divided between democrats and republicans. They are allocated among the states. Each state has electoral votes equal to the total of the 2 representative the state has in the U.S. Senate plus the number of representative the state has in the House of Representatives. Since every state has two senators and at least one representative to the House, every state has at least 3 electoral votes. Each state then votes that states electoral votes for the U.S. presidential candidate who won the election in that state.
